Subtract the polynomials.

(4a2+9b5) - (-2a2-6b5)

To subtract polynomials, we need to combine like terms. In this case, we have two polynomials: (4a^2 + 9b^5) and (-2a^2 - 6b^5).

First, let's remove the parentheses around the second polynomial by distributing the negative sign:
-1 * (-2a^2 - 6b^5) = 2a^2 + 6b^5

Now, we can combine like terms. The like terms are the terms with the same variables raised to the same powers. In this case, we have a^2 in both polynomials and b^5 in both polynomials.

So, we can subtract the coefficients of each like term:
(4a^2 + 9b^5) - (2a^2 + 6b^5) = 4a^2 - 2a^2 + 9b^5 - 6b^5

Subtracting the coefficients of a^2, we get: 4a^2 - 2a^2 = 2a^2

And subtracting the coefficients of b^5, we get: 9b^5 - 6b^5 = 3b^5

Therefore, the result of subtracting the polynomials (4a^2 + 9b^5) - (-2a^2 - 6b^5) is 2a^2 + 3b^5.

4a^2 + 9b^5 + 2a^2 + 6b^5=6a^2 + 15b^5 =

3(2a^2+5b^5).
