(-4+1)(x+8)

OpenStudy (anonymous):

3x+24

OpenStudy (anonymous):

* -3x-24

OpenStudy (stormfire1):

use the same steps as before nikkiem....and then simplify to get what QED posted

OpenStudy (anonymous):

the first term that i would start off with is -4x*x which is going to be -4x to the 2nd power right

OpenStudy (anonymous):

(-4+1) = -3 -3(x+8) = -3x-24

OpenStudy (stormfire1):

There's only 1 x in the equation...so don't add x's :)

OpenStudy (anonymous):

so then it would be 5x right ?

OpenStudy (stormfire1):

no...-4 * x is the same as -4 * 1x which = -4x

OpenStudy (stormfire1):

Here's what you should get after FOILing: -4x + 1x + 8 -32

OpenStudy (stormfire1):

which simplifies to -3x-32

OpenStudy (anonymous):

so i thought i need like four numbers in there for the answer>

OpenStudy (stormfire1):

You had 4 terms at the end...but in this case, they could be simplified to 2.

OpenStudy (stormfire1):

-4x + 1x + 8 -32 => -3x-24

OpenStudy (anonymous):

alright thanks but it was still the wrong ans.

Read through this if it's still not clear...it's a quick read: http://www.freemathhelp.com/using-foil.html
