Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I'm having trouble solving this one. I just don't really see what i'm doing wrong.

1. The problem statement, all variables and given/known data

X² - x - 2

X² + 5x + 6

2. Relevant equations

3. The attempt at a solution

(( x-1 ) * x² + 5x + 6 ) - (( x + 5 ) * x²-x-2 )

( x² + 5x + 6)²

So 8x² -6x-16

(x² + 5x + 6)²

Now I know this isn't the correct awnser. Because it should say

6x² + 16x + 4

( x² + 5x+6)²

Could anyone point out to me what i'm doing wrong?

Thanks in advance.

Tim
