Answer:

(3x2 + 3x - 1) • (x + 2)

Step-by-step explanation:

3.4 Polynomial Long Division

Dividing : 3x3+9x2+5x-2

("Dividend")

By : x+2 ("Divisor")

dividend 3x3 + 9x2 + 5x - 2

- divisor * 3x2 3x3 + 6x2

remainder 3x2 + 5x - 2

- divisor * 3x1 3x2 + 6x

remainder - x - 2

- divisor * -x0 - x - 2

remainder 0

Quotient : 3x2+3x-1 Remainder: 0
