Explanation:

Step1: Remove parentheses

$2a^2 + 2a - 3 + 3a^2 + 3a - 4 - 5a^2 - 7a - 6$

Step2: Combine like $a^2$ terms

$(2a^2 + 3a^2 - 5a^2) = 0a^2 = 0$

Step3: Combine like $a$ terms

$(2a + 3a - 7a) = -2a$

Step4: Combine constant terms

$(-3 - 4 - 6) = -13$

Step5: Combine all results

$0 - 2a - 13$

Answer:

$-2a - 13$
