Determine the sum of the polynomials below

Question

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

Answer 1

To find the sum of the two polynomials, we need to add the corresponding terms.

(3x^2+5x-4)+ (-2x^2+2x-5)
= (3x^2 + (-2x^2)) + (5x + 2x) + (-4 - 5)
= 1x^2 + 7x - 9

So, the sum of the two polynomials is 1x^2 + 7x - 9, or simply x^2 + 7x - 9.
