Question

What will I get for the answer 12(2x2−8)+13(6x2−3)

Answer 1

3x^2-5

Explanation:

i found out myself after searching the question

Answer 2

102x^2 - 135

Explanation:

Here we must follow order of operations rules:

1. Anything enclosed inside parentheses must be done first

2. Multiplication before addition/subtraction

Thus, 12(2x^2−8)+13(6x^2−3) becomes (after multiplication):

24x^2 - 96 + 78x^2 - 39

The next step is to combine like terms:

102x^2 - 135

This cannot be simplified further. 102 and 135 have no common factors.

Thus, 12(2x^2−8)+13(6x^2−3) = 102x^2 - 135
