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

[tex]3x^2+5+3-7x^2\\3x^2-7x^2+5+3[/tex]

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

[tex]-4x^2+8[/tex]

Then factor,

[tex]-4(x^2-2)[/tex]
