Question

What polynomial should be subtracted from 7x2−6x+5 to get the difference equal to x2−x.

Answer 1

`6x^2-5x+5` should be subtracted.

Explanation:

we find the polynomial that is subtracted from 7x^2-6x+5 to get the difference equal to x^2-x

7x^2-6x+5-polynomial=x^2-x

To get the polynomial subtract x^2-x from the given polynomial

`7x^2-6x+5 - (x^2-x)=  7x^2-6x+5-x^2+x`

`6x^2-5x+5`

So
`6x^2-5x+5` should be subtracted.
