(3x2 - 4x +8)+(-x2 – 2x – 8)

Hey there,

The question given is as follows:

(3x² - 4x + 8) + (-x² - 2x - 8)

When we add polynomials we add like terms (e.x. we add 3x² with -x²) and combine the two to make one polynomial. When we add the two polynomials given above:

2x² - 6x + 0

So our answer to the problem would be 2x² - 6x.

Hope I helped,
