Question

Find the remainder when p(x) =x³+4x²-3x is divided by x+4​

Answer 1

Answer:

12

Step-by-step explanation:

By remainder theorem:

STEP 1: Get the root of the divisor

x + 4 = 0

x = -4

STEP 2: Substitute the derived value in step 1 to the dividend

= x^3 + 4x^2 - 3x

= (-4)^3 + 4(-4)^2 - 3(-4)

= -64 + 64 + 12

= 12
