Given the numerical equation:

(x^2 + 3x - 7) + 2(3x^2 + 3x + 2)

Solution:

In order to solve the numerical equation, we simply need to distribute first 2, to each value in its corresponding parenthesis.

= (x^2 + 3x - 7) + 2(3x^2 + 3x + 2)

= x^2 + 3x - 7 + 6x^2 + 6x + 4

Combine similar terms.

= 7x^2 + 9x - 3 + 6x^2

Final answer:

= 7x^2 + 9x - 3 + 6x^2
