so I have this

-2 - [1 - 2]^2

the answer is -1

this is where i get confused... i know that 1 - 2 is -1, square that -1^2 is positive 1 so it's going to look like this.... -2 - 1.... why am i getting -3 when the correct answer is -1....

the original equation is this, (-2y)(-2x) - [1 - 2x - 2y]^2...... where you plug in values of x and y...... x=0 and y=1
