Factor the following polynomial completely.

-x^2 y^2 + x^4 + 4y^2 - 4x^2

a) (x - 2)(x - 2)(x + y)(x - y)
b) (x + 2)(x + 2)(x + y)(x - y)
c) (x + 2)(x - 2)(x + y)(x - y

215.92 dollars is the answer

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
