Simplify (8x2 − 1 + 2x3) − (7x3 − 3x2 + 1). −5x3 + 11x2 − 2 5x3 − 11x2 + 2 x3 + 2x2 + x3 x3 − 2x2 − x3

-5x^3 +11x^2-2

Step-by-step explanation:

(8x^2 − 1 + 2x^3) − (7x^3 − 3x^2 + 1)

Distribute the minus sign

(8x^2 − 1 + 2x^3) − 7x^3 + 3x^2 - 1

I like to line them up vertically from largest to smallest

 2x^3 + 8x^2 − 1

− 7x^3 + 3x^2 - 1

-5x^3 +11x^2-2
