Question

1. Solve using long division.

(9x3 - 48x2 + 13x + 3) = (x - 5)
9x2 – 3x – 2, R-7
O
9x2 - 2x - 2, R-6
9x2 - 4x - 2, R-8
9x2 - x - 2, R-5

Answer 1

9x^2 - 3x - 2, R -7.

Explanation:

x - 5) 9x^3 - 48x^2 + 13x + 3(9x^2 - 3x - 2 <---- Quotient.

9x^3 - 45x^2

- 3x^2 + 13x

-3x^2 + 15x

-2x + 3

-2x + 10

-7 <----- Remainder
