Simplify the expression in picture

6x^2 + -10

Step-by-step explanation:

Hi there! I'm glad I was able to help you answer this polynomial expression!

All we're really doing to solve is combine like terms.

(5x^2+2) - (-4x^2+7) + (-3x^2-5) =

5x^2 + 2 + 4x^2 + -7 + -3x^2 + -5

(5x^2 + 4x^2 + -3x^2) + (2 + -7 + -5)

6x^2 + -10

The terms that have x^2 at the end are in bold letters so you know what we're combining them - the other numbers are the separate like terms.

Simplified, our answer is 6x^2 + -10.
