Question

find the remainder when 4x power 3 - 3 x power2 plus 4 x - 2 is divided by (i) x-3 (ii) x-5​

Answer 1

Answer:

(i) 91 (ii) 443

Step-by-step explanation:

Given f(x) = 4x^3-3x^2+4x-2

• Use the zero product rule

(i) x-3

x-3=0 (zero product rule)

Therefore x=3

Putting x=3 in f(x), you get remainder = 91

(ii) x-5

x-5=0 (zero product rule)

Therefore x=5

Putting x=5 in f(x), you get remainder= 443
