Question

Find the remainder when x³-3x²+3x-1is divided by x+3​

Answer 1

Answer:

Remainder = -64

Step-by-step explanation:

By remainder theorem

Given,

(x + 3) i.e, x + 3 = 0.  therefore, x = -3

let f(x) = x³ - 3x² + 3x - 1    [now put the value of x]

f(-3) = (-3)³ - 3(-3)² + 3 x (-3) - 1

      = {(-3) x (-3) x (-3)} - {3 x (-3) x (-3)} - 9 - 1

      = (-27) - 27 - 10

      = -64
