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

e[*SUP}2[*/SUP]
No "*" and use ] instead of the } (which, I assume, was a typo)
e2
[*tex]e^2[*/tex]
No "*".
e^2

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.
