Best ResponseYou've already chosen the best response.1im guessing you have to expand this...??

Best ResponseYou've already chosen the best response.0Not really sure if i do or not all they gave me was (x+6)^2?

Best ResponseYou've already chosen the best response.0Have you ever done problems that asked you "to expand" an expression?

Best ResponseYou've already chosen the best response.0Lets start from this. \(\large\color{black}{\rm \displaystyle expression\text{#}1(expression\text{#}2) }\) is same thing as \(\large \color{black}{\rm expression\text{#}1~\cdot~expression\text{#}2}\) you know that right?

Best ResponseYou've already chosen the best response.0? What is expression 1 and 2 suppose to mean?

Best ResponseYou've already chosen the best response.0any expreesions, i am just naming them like this.

Best ResponseYou've already chosen the best response.0this is equivalent to saying a(b) is same as saying a•b

Best ResponseYou've already chosen the best response.0So, if I say a(b), then I know that it is a•b and it would be the same thing as a•b.

Best ResponseYou've already chosen the best response.0now, if I said: a(b+c), then what am I really doing? a(b+c) = a•(b+c) = a•b+a•c=ab+ac

Best ResponseYou've already chosen the best response.0Yeah, just not sure what this has to do with the problem i asked.

Best ResponseYou've already chosen the best response.0\(\large (x+6)^2 \implies (x+6)(x+6)\implies \begin{cases} x\cdot x\implies &?\\ x\cdot 6\implies &?\\ 6\cdot x\implies &?\\ 6\cdot 6\implies &? \end{cases}\)

Best ResponseYou've already chosen the best response.0Okay think i got it. x*x = X^2, x*6 = x^6, 6*x= 6x and 6*6 = 36

Best ResponseYou've already chosen the best response.2(x+6)^2 is the same as (x+6)*(x+6) squaring something means you're multiplying it by itself To expand out (x+6)*(x+6) you can use the FOIL rule but I like a table better because you can use a table for things that FOIL can't do dw:1437695027927:dw

Best ResponseYou've already chosen the best response.2To fill out the table, you multiply the headers example: x times x = x^2 dw:1437695125576:dw

Best ResponseYou've already chosen the best response.2you said `x*x = X^2, x*6 = x^6, 6*x= 6x and 6*6 = 36` so this is reflected in the table dw:1437695217158:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.2The last thing to do is add up x^2, 6x, 6x, and 36 (all the terms found in the table). Combining like terms if any.

Best ResponseYou've already chosen the best response.2oh just noticed you wrote `x*6 = x^6` it should be x*6 = 6x

jim_thompson5910

Best ResponseYou've already chosen the best response.2what do you get when you add up x^2, 6x, 6x, and 36

jim_thompson5910

Best ResponseYou've already chosen the best response.2you can't combine 6x with 36 to get 42x

jim_thompson5910

Best ResponseYou've already chosen the best response.26x and 36 aren't like terms

Best ResponseYou've already chosen the best response.0Were adding right? 12x^2

Best ResponseYou've already chosen the best response.2the x doesn't become x^2 when you add 6x+6x

jim_thompson5910

Best ResponseYou've already chosen the best response.2so we get x^2+12x+36

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2that's as far as we can go because there are no other like terms left to combine
