Simplify the polynomial by combining like terms. Make sure your anwser is in standard form: 4x + 7 - 8x (2) + 2x + 5x (2) - 11 Also, keep in mind that the numbers that are in parenthesis are the exponents. ​

therefore

we can see the expression is in standard form since a,b and c is -3,6 and -4

also let's justify it

substitute the value of a,b and c respectively

(-3)x²+(6)x+(-4)

-3x²+6x-4 (proven)

Look i don’t know the answer to this but someone else will so just wait a little bit longer
