how to you factor -4x^2

not much to do except note that

-4x^2 = (-4)(x)(x)

Is there more to this?

I guess you could say it's also -(2x)^2

To factor -4x^2, we need to find the common factors of the terms. In this case, we have only one term, so we will be factoring a quadratic expression.

First, we need to start by factoring out the greatest common factor, which is -4:

-4x^2 = -4(x^2)

Since there is no common factor other than -4, we cannot factor the expression further. So, the factored form of -4x^2 is -4(x^2).
