Question

Using Remainder theorem, find the remainder when 2x
3 – 4x
2 + 2x – 5 is divided by
x – 3.

Answer 1

Answer:

21

Step-by-step explanation:

2(3)3-4(3)2+ 2(3)-5

2(27)-4(9)+6-5

54-36+1

57-36

21

Answer 2

Answer:

19

Step-by-step explanation:

x-3=0

X=3

p(X)= 2x^3-4x^2+2x-5 = Remainder

p(X)= 2×3^3-4×3^2+2×3-5 = Remainder

p(X)= 2×(27)-4×(9)+1 = Remainder

p(X)= 54-36+1= Remainder

p(X)= 55-36= Remainder

p(X)= 19= Remainder
