Answer 1

Answer:

$2x^2-2x+7$

Step-by-step 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 $2x^2-2x+7$
