Solution for y=(x-8)(x-4) equation: 


Simplifying
y = (x + -8)(x + -4)

Reorder the terms:
y = (-8 + x)(x + -4)

Reorder the terms:
y = (-8 + x)(-4 + x)

Multiply (-8 + x) * (-4 + x)
y = (-8(-4 + x) + x(-4 + x))
y = ((-4 * -8 + x * -8) + x(-4 + x))
y = ((32 + -8x) + x(-4 + x))
y = (32 + -8x + (-4 * x + x * x))
y = (32 + -8x + (-4x + x2))

Combine like terms: -8x + -4x = -12x
y = (32 + -12x + x2)

Solving
y = 32 + -12x + x2

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying
y = 32 + -12x + x2
