Question

3. Use Remainder theorem to find the remainder when f(x) is divided by g(x) in the
following:
(i)f(x) = 8x3 – 4x2 + 2x – 1, g(x) = 1 - 2 x

Please please answer it

Answer 1

Answer:

g(x)= 1-2x

1=2x

1/2 = x

Putting value of x in f(x).

F(x)=8×3-4×2+2x-1

= 24-8+2(1/2)-1

= 24-8+1-1

=24-8

F(x) = 16

Answer 2

Answer:

g(x)= 1-2x = 0

x = -1/2

f(x)= 24-8+2*-1/2-1

= 16-1-1

= 16-18

= -2
