1. Evaluate (-x) ^ 2 which means (-x) to the power of 2 or square and compare this to - (x^2). Use x=5.
(-x)^2 = (-x)(-x) = (-1)(-1)(x)(x) = x^2
All values when plugged in for x will be positive.
-(x)^2 = -1(x)(x) = -x^2
All values when plugged in for x will be negative.
(-x)^2 = (-5)^2 = 25
-(x)^2 = -(5)^2 = -25
Red: (-x)^2
Green: -(x)^2
