Question

How much greater is `(-7x^2 + 14x + 17) + (19x^2 - 6x - 20) + (-14x^2 - 18x + 20) + (20x^2 + 19x + 17)`?

Answer 1

We can simplify the expression. See below:

Explanation:

What we can do with what is here is simplify the expression:

`-7x^2+14x+17+19x^2-6x-20-14x^2-18x+20+20x^2+19x+17`

Group like terms:

`(-7+19-14+20)x^2+(14-6-18+19)x+(17-20+20+17)`

`18x^2+9x+34`
