Question

What is the remainder when (2x3 – 8x2 + 6x – 16) ÷ (x – 4) ?

Answer 1

use the remainder theorem

if dividing by x -a then P(a) will give the remainder for the polynomial P(x)


in your question

\[P(x) = 2x^3 -8x^2 + 6x - 16\]

and the divisor is (x - 4)

so find

P(4)

Answer 2

unfortunately ive forgotten how to

Answer 3

well you just do some substitution replace x with 4 and then evaluate....
