Question

Find the remainder by Remainder theorem, when p(x) = x⁴-3x + 2x + 1 is divided bv 2x-1​

Answer 1

Answer:

Let

f

(

x

)

=

x

3

+

k

x

2

+

x

+

5

When

f

(

x

)

is divided by

(

x

+

2

)

, the remainder is

=

3

This is the remainder theorem

so,

f

(

−

2

)

=

−

8

+

4

k

−

2

+

5

=

3

4

k

=

3

+

5

=

8

k

=

2
