2a² + 6a=8
2a² + 6a - 8=0
2(a² + 3a - 4) = 0
2(a-1)(a+4) = 0
(a-1)(a+4) = 0
a = 1 a = -4
It's been a while since I've actually done this. I'll be needing to know this later. But I think that's your answer. Looks right. Although you probably did this already...

I believe a=1
2 (1)^2 + 6(1)=8
2(1) + 6(1)=8
2+6=8

Here's another star for making me feel totally inadequate. I will probably be impotent for weeks now. ( I know there is 24 cans of beer in a case!)
