f(x)=x^2+5x+7 f(3a4) = (3a4)^2 + 5(3a 4) + 7 Simplify the expression

Bro, the first term is negative

However there is a negative sign in fron of x so you have to multiply the first term with negative one.

I know how to do foil and all the math yet are you solving for x or leaving it as a quadratic?

Nothing nowhere says to solve for x. In fact, when I posted the hint I gave you. I left a comment below saying to "simplify the expression". How did you interpret "solve for x" from that?

StephchenBest ResponseYou've already chosen the best response.0
x becomes a, so x is out of the picture. if your asked to simplify the expression then I guess all you have to do is the equation hero did setup for you.

kelsey1Best ResponseYou've already chosen the best response.0
Well I meant "a" and my problem was that I thought I was solving for "a".
