Determine the sum of the polynomials below.

Question

(-12a^2+11a+9)+(6a^2-5a-6)=

Answer 1

To find the sum of these polynomials, we need to combine like terms.

(-12a^2+11a+9)+(6a^2-5a-6)

To combine like terms, add the coefficients for each corresponding term.

(-12a^2 + 6a^2) + (11a - 5a) + (9 - 6)

Simplifying further:

-6a^2 + 6a + 3
