What is the largest of three consecutive positive integers if the product of the smaller two integers is seven less than three times the largest integer?
Why is this NOT the equation?
x*(x+1) = 3*(x+2) -7
I swear no matter how many times I read this problem I still come up with this equation but this equation doesn't allow me to solve for x. GRRR
What am I doing wrong?

You're good; just keep solving that equation.
X^2 + x = 3x + 6 - 7
X^2 -2x +1 = 0
(x-1)(x-1) = 0
X=1
Then check it in the original equation, and make sure you are answering the question.

Thank you! That makes me feel a little better. I forgot about factoring, it's been awhile.
