Answer 2

Answer: -4(x^2-2) or -4x^2+8

Step-by-step explanation:

Addition and Subtraction second degree Polynomials & Factorization and it also requires PEMDAS too.

Remove the brackets so it's easier to calculate

$3x^2+5+3-7x^2\\3x^2-7x^2+5+3$

Arrange degree (Not important) (If you are expert then no need to.)

$-4x^2+8$

Then factor,

$-4(x^2-2)$
