Answer:

Given, a polynomial 9x

2

−3x

2

+x−5 divided by x−

3

2

.

Then divided by x−

3

2

so x−

3

2

=0 or x=

3

2

.

Replace x by

3

2

, we get,

p(x)=9x

3

−3x

2

+x−5

p(

3

2

)=9(

3

2

)

3

−3(

3

2

)

2

+(

3

2

)−5

⟹ p(

3

2

)=9×

27

−3×

9

4

+

3

2

−5

⟹ p(

3

2

)=

27

72

12

+

3

2

−5

⟹ p(

3

2

)=

27

72−36+18−135

=

27

−81

=−3.

Therefore, the required remainder is −3.
