Question

What is the difference of the two polynomials (9x^2+8)-(2x^2+3x)

Answer 1

`5x {?}^(2) + 8 - 3x`

`9x {?}^(2) + 8 - (4x {?}^(2) + 3x) \\ 9x {?}^(2) + 8 - 4x - 3x \\ 5x {?}^(2) + 8 - 3x`

Answer 2

7x^2 -3x +8

Explanation:

(9x^2+8)-(2x^2+3x)

Distribute the minus sign

(9x^2+8)-2x^2-3x)

Combine like terms

9x^2 -2x^2 -3x+8

7x^2 -3x +8
