Answer:

The value of a is 5.

Step-by-step explanation:

Given the polynomial 2x^3-2x^2+x-a

when the above polynomial is divided by x-2 leaves the remainder 5.

we have to find the value of a

By remainder theorem, when f(x) is divided by (x-a), remainder is f(a).

The polynomial f(x)=2x^3-2x^2+x-a is divided by x-2 leaves the remainder 5.

Here, f(2)=5

2(2)^3-2(2)^2+2-a=5

⇒ 16-8+2-a=5[/tex]

a=5
