Question

Find the difference between the polynomials (5x^2+ 9x-10) - (2x^2-3+4)

Answer 1

To find the difference between the two polynomials, we need to subtract the second polynomial from the first.

(5x^2 + 9x - 10) - (2x^2 - 3 + 4)
= 5x^2 + 9x - 10 - 2x^2 + 3 - 4
= 5x^2 + 9x - 10 - 2x^2 - 1
= (5x^2 - 2x^2) + 9x + (-10 - 1)
= 3x^2 + 9x - 11

Therefore, the difference between the two polynomials (5x^2 + 9x - 10) and (2x^2 - 3 + 4) is 3x^2 + 9x - 11.
