Answer 1

`2x^2-2x+7`

Explanation:

First rearrange the equation so all similar variables are together (all the
`X^2` all the x's and all the numbers without an x)

`3x^2-x^2+6x-8x-4+11`

Then do addition and subtraction

`3x^2-1x^2=2x^2\\6x-8x=-2x\\and\\-4+11=7\\`

Then we put it all together to get the finally result of
`2x^2-2x+7`
