Answer 2

The answer in descending powers of x:

• -2x²+2x+7

Explanation:

We have to subtract
`2x^2-6x-4` from
`4x^2-4x+3`

`4x^2-4x+3\:-\left(2x^2-6x-4\right)`

Distribute the Negative Sign

`=4x^2-4x+3+-1\left(2x^2-6x-4\right)`

`=4x^2+-4x+3+-1\left(2x^2\right)+-1\left(-6x\right)+\left(-1\right)\left(-4\right)`

`=4x^2+-4x+3+-2x^2+6x+4`

Combine Like Terms

`=4x^2+-4x+3+-2x^2+6x+4`

`=\left(4x^2+-2x^2\right)+\left(-4x+6x\right)+\left(3+4\right)`

`=2x^2+2x+7`

Thus, the answer in descending powers of x:

• -2x²+2x+7
