Answer:
[tex]2x^2-2x+7[/tex]
Step-by-step explanation:
First rearrange the equation so all similar variables are together (all the [tex]X^2[/tex] all the x's and all the numbers without an x)
[tex]3x^2-x^2+6x-8x-4+11[/tex]
Then do addition and subtraction
[tex]3x^2-1x^2=2x^2\\6x-8x=-2x\\and\\-4+11=7\\[/tex]
Then we put it all together to get the finally result of [tex]2x^2-2x+7[/tex]
