What is the difference of the two polynomials?

(9x2 + 8x) – (2x2 + 3x)

1 answer

To find the difference of the two polynomials, we can first distribute the negative sign in front of the second polynomial:

(9x^2 + 8x) - (2x^2 + 3x)
= 9x^2 + 8x - 2x^2 - 3x
= (9x^2 - 2x^2) + (8x - 3x)
= 7x^2 + 5x

Therefore, the difference of the two polynomials is 7x^2 + 5x.
