Find the remainder when the polynomial 9x^2 - 4x - 7 is divided by x - 3.

62

Step-by-step explanation:

A polynomial f(x) divided by (x - a) has remainder f(a)

f(x) = 9x² - 4x - 7 is divided by (x - 3) , then remainder is

f(3) = 9(3)² - 4(3) - 7 = 9(9) - 12 - 7 = 81 - 19 = 62

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
