Factor the following polynomial complete -x^2y^2+x^4+4y^2-4x^2

Step-by-step explanation:

First, see if you can group the terms. I will first put this in LaTeX to make it easier to understand. We have , and we can factor a out of the first group, and a out of the other group, to get Let's multiply everything by -1 now to ge t Multiplying all this does not change it, because -1^2=1.

Because a^2-b^2=(a+b)(a-b), we get out final answer as .

the answer is mc^1-1jpeg
