Answer in detail. Please help me very much I give 15 points only help 7(a^2-2)-4(a+3)(a-3)-3a^2-22+10(a^2-15)-12(a-4)(a+4)-42+2a^2

To solve this problem, we need to simplify the expression by expanding the brackets and combining the like terms. Here are the steps:

7(a^2-2)-4(a+3)(a-3)-3a^2-22+10(a^2-15)-12(a-4)(a+4)-42+2a^2

= 7a^2-14-4(a^2-9)-3a^2-22+10a^2-150-12(a^2-16)-42+2a^2

= 7a^2-14-4a^2+36-3a^2-22+10a^2-150-12a^2+192-42+2a^2

= -2a^2-42

So, the final answer is -2a^2-42.
