Complete the following Operations?

[Smokinoakum]

Hi guys...It's me again. I have a few problems that I'm confused about. The instructions say "Complete the following operations."

Here are the problems.

1. (8x+3)^2

2. (4x-7)(4x+7)

Is he asking to "expand" the problems? If so this is what I came out with...

1. (8x+3)^2 = 64x^2 + 48x + 9

2. (4x-7)(4x+7) = 16x^2 - 49

Am I understanding both his instructions, and the process?

Thanks again.

Neil

\(\displaystyle Yes, \ \ it \ \ would \ \ mean \ \ expanding.\)


1. (8x+3)^2 = 64x^2 + 48x + 9

\(\displaystyle . . . . . How \ \ did \ \ you \ \ know \ \ to \ \ do \ \ this \ \ without \ \ typing \ \ (8x + 3)(8x + 3) \ \\)
\(\displaystyle as \ \ an \ \ intermediate \ \ step?\)

It's is on my scratch piece of paper. Should I include it in my answer?
