Factor out a 2 to start.
Okay.. I did that
So then you divide by the 2 and end up with 6x^2 - 5x - 6 = 0
Then you would use the AC method.
is that where you take the coefficient of the first term and multiply it with the last term and find two multiples that add to equal the middle term?
haha okay well I did that from the get go, but I'm left with 36?
Sorry I was trying to fix a printer haha
it's okay.. I totally understand. I'm just thankful someone replied!
Actually I lied haha, wrong method sorry. Well, right method but in the wrong way. Step 1: Multiply your first term by your last term: 6 x 6 = 36
Step 2: Find two integers when multiplied together get 36, but when added together equal your middle term: 5 -4 and 9
OMG! I feel like the biggest idiot! I so had that I just didnt even thing about making the four negative wow. you probably think I'm so dumb lol
Step 3: Rewrite the middle term by replacing the (5x) with the two numbers chosen. (-4 and 9) 6x^2 -4x +9x + 12 = 0
Not at all :) Do you know where to go from there?
Yes:] I do.. Thank you So much! And you better not go anywhere.. I'm sure I will need you again.. I have 50 more to go lol
Haha alright :) I think I will write the rest of the steps anyway just in case anyone else needs to know how to do the AC method.
I have another one..
I'm sure you're going to think I'm dumb again.. lol
I didn't think you were dumb in the first place..
Did it not post?
2x^2+X-15=0 This seriously looks as easy as the first one.. Thats sweet of you to not think I'm dumb lol
so what are you trying to find terms for?
Are you using the AC method? First term times last term? 2 X 15 So you are looking for terms that multiply to get 30 and add up to get your middle term, which in this case is 1
It doesnt specify which method to use.. But I'm sure thats what it is lol
Whenever you are trying to factor and you have a number in front of your x^2 term, you are going to want to use the AC method :)
So do you know where to go from there?
oh.. haha so find numbers that when multiplied get 30 and add up to 1
Sorry my laptop froze.. Anyways I got 6 and -5 ... Duh!
Sorry, my internet went out, and my tutee came haha So, do you know where to go from there?
Tutee? And yes I finished it.. I'm not going to do the rest of my paper though.. I'm just gonna turn it in as is haha
Yeah, I am a math tutor. :) And you really should finish :/
Aweee! That's awesome! You can tutor me too lol.. Anyways I'm excused from class because of a death in the family but I still have to turn it in before seven
