Question

please help me with this math problems

Answer 1

The answer is -2x^2-7x-11
you just have to add the ones that have the same variable with the same exponent. so you would add -5x^2 and 3x^2 which is -2x^2.
Then you add -3x and -4x which is -7x.
in the end you only have to add -8 and -3 which is -11
