    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)
