Question

1. Use synthetic division to divide f(x) = x^3 - 11x^2 + 26x - 16 by x -8. Find all zeros.

2. Solve the equation 3x^3 - 26x^2 + 61x - 30 = 0 given that 3 is a 0.

Answer 1

First, you need to find the zero, so solve for x when it equals 0.
x-8=0

Answer 2

Yup, got that part down. x = 8, so 8 is the dividend.

Answer 3

Yep. Now:
8| 1 -11 29 -16
