Question

Divide the polynomial (3x3 + 2x2 - 1) by (x + 2)​

Answer 1

Step-by-step explanation:

3x^3 + 2x^2 - 1 ÷ x + 2

1. 3x^3 + 2x^2 - 1 divided by x + 2

multiply by 3x^2

and we get 3x^3 + 6x^2

and subtract it

-4x^2 -1

2. -4x^2 - 1 divided by x + 2

multiply -4x

-4x^2 - 8x

-7x

3x^2 - 4x
