Simplify: (x - 4)2

OpenStudy (uri):

2x-8.

OpenStudy (goldphenoix):

\[\large \large (x-4)^2 = (x-4)(x-4)\] Do you know how to do the FOIL method?

OpenStudy (anonymous):

Is this correct? x2 - 8x + 16 @GoldPhenoix

OpenStudy (goldphenoix):

Yes. Good job. :)

OpenStudy (anonymous):

Can you help me with this one too? (3x + 12) (3x - 12) I'm kind of confused. @GoldPhenoix

OpenStudy (goldphenoix):

What did you get?

OpenStudy (anonymous):

9x^2 + 36x - 144. I know it's wrong but I don't see how you can get a different answer... @GoldPhenoix

OpenStudy (goldphenoix):

|dw:1374167515322:dw|

OpenStudy (anonymous):

So then it would just be 9x^2 - 144? @GoldPhenoix

OpenStudy (goldphenoix):

Yes.
