Question

Find the remainder when f(x) = x3 − 14x2 + 7x − 10 is divided by x − 3.

Answer 1

Answer: -88

Step-by-step explanation:

To find the remainder, you can use long division, synthetic division, or input the x-value.  I am going to input because it is the fastest method.

f(x) = x³ - 14x² + 7x - 10           divided by x - 3 = 0 ---> x = 3

f(3) = 3³ - 14(3)² + 7(3) - 10

     = 27 - 126  + 21 - 10

     = -88
