How do I use the distributive law to factor 2a + 2b?

Best ResponseYou've already chosen the best response.0each term has a 2 in it, so you can take that out of it. dividing each term by 2 leaves (a+b) inside. so we have 2a+2b=2(a+b)

Best ResponseYou've already chosen the best response.0well, what's the largest factor that is in both terms?

Best ResponseYou've already chosen the best response.08 doesn't go into 4 though. try a little smaller

Best ResponseYou've already chosen the best response.0:) warmer? it's bigger than that.

anonymous

Best ResponseYou've already chosen the best response.0precisely. now, divide each term by 4, and this is what will be left inside the parentheses, and you take the four out.

Best ResponseYou've already chosen the best response.032/4 is 8 and 4/4 is 1....how would i write that out?

Best ResponseYou've already chosen the best response.0don't forget the x in the first term! but it will become 4(8x+1)

Best ResponseYou've already chosen the best response.0do you see what happened there? we can do more until you get a good handle on it.

Best ResponseYou've already chosen the best response.0Why is it written out like that...?

anonymous

Best ResponseYou've already chosen the best response.0because now, because of the distributive law, the 4 will be distributed to both of the terms. that means we will get 4(8x+1)=4*8x+4*1=32x+4 which is what we started with

Best ResponseYou've already chosen the best response.0Ahhh, i see what you did now

anonymous

Best ResponseYou've already chosen the best response.0and notice that 8x and 1 don't have any common factors that we can take out; the idea is to take out the "biggest" thing we possibly can

anonymous

Best ResponseYou've already chosen the best response.0so, for practice, factor this (it's a little different than the others): 3x^2+9x

anonymous

Best ResponseYou've already chosen the best response.0first step; identify the largest factor which is in both

Best ResponseYou've already chosen the best response.0i'm gonna guess 1? 1 goes into all three?

anonymous

Best ResponseYou've already chosen the best response.0oh wait i think you misread it. that 2 is an exponent. it's \[3x^2+9x\]

anonymous

Best ResponseYou've already chosen the best response.0sorry for the confusion

anonymous

Best ResponseYou've already chosen the best response.0oh okay. so would it be 3?

anonymous

Best ResponseYou've already chosen the best response.0and what would it look like after taking out the three?

anonymous

Best ResponseYou've already chosen the best response.0what do you mean taking out?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0the idea is, once we find the largest thing, you "take it out" by putting the thing in parentheses, moving the thing outside of the parentheses, and dividing each term inside by whatever you took out

anonymous

Best ResponseYou've already chosen the best response.0so we divide x^2 by 3 and divide 9x by 3?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0it was 3x^2, but yes that's correct

anonymous

Best ResponseYou've already chosen the best response.0okay can we try 5x+10+15y? Because i dont really have any exponents in my homework yet.

anonymous

Best ResponseYou've already chosen the best response.0oooh okay! i'm sorry. sure, give that one a try

anonymous

Best ResponseYou've already chosen the best response.0Its fine. So, we divide by 5?

anonymous

Best ResponseYou've already chosen the best response.0Would the answer be 5(1x+2+3y)?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yep, that's it! also, 1x is typically just written as x, but your answer is still right

anonymous

Best ResponseYou've already chosen the best response.0Nice! Okay, so basically i just have to find the least factor for the numbers then divide by it?

anonymous

Best ResponseYou've already chosen the best response.0greatest factor, actually. the least would be one :P

anonymous

Best ResponseYou've already chosen the best response.0Okay. Is this correct, 7a+35b would be 7(a+5b)?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0how about 7+7y? Would it be 7(7+y)?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0you made a little error there; you see, if you multiply that out, you get 49+7y.

anonymous

Best ResponseYou've already chosen the best response.0Okay, so how would i solve this one?

anonymous

Best ResponseYou've already chosen the best response.07 is the greatest common factor of the two terms, but when you divide 7 by 7, you get 1. The y part is correct.

anonymous

Best ResponseYou've already chosen the best response.0Lol, so would it be 7(y)? im not sure how to do this one

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, our two terms are 7 and 7y, and the factor we're taking out is 7. so, when we divide 7 by 7, we get 1. This doesn't mean it disappears, it's just 1. 7y divided by 7 gives y, and so we have that 7+7y=7(1+y)

Best ResponseYou've already chosen the best response.0and you see that if you multiply out the right side using the distributive property, you do in fact get the left side.

Best ResponseYou've already chosen the best response.0Ohhhhhhhhhhhhhhh, alright, i got you

anonymous

Best ResponseYou've already chosen the best response.0OKay, i got another question lol. How do i list factors in an expression. 3(x_y) would the factors be 3 & x? since those are the only ones being multiplied?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.03(x+y) is what i ment

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0what do you mean, list factors in it? the way you have it written, that expression is already factored, and its factors are 3 and x+y

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0My homework says, List the factors in each expression and it gave me 3(x+y)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0well, I suppose that means 3 is a factor and x+y is a factor?

anonymous

Best ResponseYou've already chosen the best response.0Um, okay. i'm just gonna write that down & ask my professor tomorrow. Thanks for your help tho

anonymous

Best ResponseYou've already chosen the best response.0yeah sure. I thought if they were asking that question though, they'd give it as 3x+3y, but whatever.

anonymous

Best ResponseYou've already chosen the best response.0Yea, i don't know? i suck at math lol
