Solution for y=2(x+2)(x-2) equation: 


Simplifying
y = 2(x + 2)(x + -2)

Reorder the terms:
y = 2(2 + x)(x + -2)

Reorder the terms:
y = 2(2 + x)(-2 + x)

Multiply (2 + x) * (-2 + x)
y = 2(2(-2 + x) + x(-2 + x))
y = 2((-2 * 2 + x * 2) + x(-2 + x))
y = 2((-4 + 2x) + x(-2 + x))
y = 2(-4 + 2x + (-2 * x + x * x))
y = 2(-4 + 2x + (-2x + x2))

Combine like terms: 2x + -2x = 0
y = 2(-4 + 0 + x2)
y = 2(-4 + x2)
y = (-4 * 2 + x2 * 2)
y = (-8 + 2x2)

Solving
y = -8 + 2x2

Solving for variable 'y'.
