When the expression

1-1x+2x^2-2-3x+3x^2-4+4x-5x^2-6x+7-8x^2

written in the form ax^2 + bx + c, where a, b, and c are non-zero integers, what is the value of a + b + c?

To look at this problem more clearly, let's write it in latex... $1-1x+2x^2-2-3x+3x^2-4+4x-5x^2-6x+7-8x^2$

 

We can easily combine like terms to get $(2+3-5-8)x^2 + (-1-3+4-6)x + (1-2-4+7) = -8x^2 -6x + 2$.

 

Can you finish from here?
