(4x^2-4x-3)+(3x^2-3x-5) then (4x^2-4x--3x-5) show work on both mark brainliest

We have to add the polynomials and

To add the polynomials we need to add the like terms, by like terms we understand that the terms with the same exponent of the variables.

So in this case,

We will add the coefficients of , and constants separately, we get:

Similarly, for the polynomials

We will subtract the coefficients of like terms, we get:

b. x- 48 =120
