Guys help needed fast pls​

Answer 1

`(61)/(8)`

Explanation:

If a polynomial p(x) is divided by a factor (x + h ) then the remainder is

f(- h)

Here p(x)is divided by (x -
`(1)/(2)` ) thus evaluate p(
`(1)/(2)` ) for remainder

p(
`(1)/(2)` )

= (
`(1)/(2)` )³ - 2(
`(1)/(2)` )² + 8

=
`(1)/(8)` -
`(1)/(2)` + 8

=
`(61)/(8)`
