Question

Find the remainder when x³+x²+x+1 is divided by x -1/2 using remainder theorem

Plz help me.......

Answer 1

Answer:

x-1=0

x=1

p(x)=(x)the power 3 +(x)the power2+(x)+1

p(1)=1the power 3+1the power 2+1+1

=1+1+1+1

R=4

Answer 2

Answer:

15/8

Step-by-step explanation:

$p(x) = {x}^{3} + {x}^{2} + x + 1$

To find ,

remainder when p(x) is divided by x-1/2

By remainder theorem,

remainder will be equal to p(1/2)

p(1/2) = 1/8+1/4+1/2+1

= 15/8 (Answer)
