Question

Find the remainder when 2x square-2x-3

Answer 1

Step-by-step explanation:

Given polynomial 2x

2

−3x+5 is divided by 2x−3

Then 2x−3=0 or x=

2

3

Replace x by

2

3

we get

p(x)=2x

−3x+5

p(

⇒p(

18−18+20

⇒p(

)=5

Thus remainder is 5

Then the value of polynomial 2x

2

−3x+5 is not zero by polynomial 2x−3

So 2x−3 is not the factor of polynomial 2x

2

−3x+5
