Where did I go wrong with this?

-2e(e + 3) + 4 (e + 2)

My answer is - 2e - 6e + 8
According to my book it should be - e - 3e + 6

correction
question is:
-2e(2 + 3) + 4(e squared + 2)
my wrong answer:
+2e squared + 6e + 8
right answer:
e squared - 3e + 6
 
e[*SUP}2[*/SUP]
 
[*tex]e^2[*/tex]

No "*" and use ] instead of the } (which, I assume, was a typo)
e2

No "*".

Please post the correct problem. You have so many corrections and changes, that I can't tell what you're trying to simplify.

If you understand the distributive property -- a(b + c) = ab + ac -- and combining like terms, this problem is straightforward.
