Solution for y=0.5(x-5)(x-12) equation: 


Simplifying
y = 0.5(x + -5)(x + -12)

Reorder the terms:
y = 0.5(-5 + x)(x + -12)

Reorder the terms:
y = 0.5(-5 + x)(-12 + x)

Multiply (-5 + x) * (-12 + x)
y = 0.5(-5(-12 + x) + x(-12 + x))
y = 0.5((-12 * -5 + x * -5) + x(-12 + x))
y = 0.5((60 + -5x) + x(-12 + x))
y = 0.5(60 + -5x + (-12 * x + x * x))
y = 0.5(60 + -5x + (-12x + x2))

Combine like terms: -5x + -12x = -17x
y = 0.5(60 + -17x + x2)
y = (60 * 0.5 + -17x * 0.5 + x2 * 0.5)
y = (30 + -8.5x + 0.5x2)

Solving
y = 30 + -8.5x + 0.5x2

Solving for variable 'y'.

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