Solution for y=0.6(x-3)(x-9) equation: 


Simplifying
y = 0.6(x + -3)(x + -9)

Reorder the terms:
y = 0.6(-3 + x)(x + -9)

Reorder the terms:
y = 0.6(-3 + x)(-9 + x)

Multiply (-3 + x) * (-9 + x)
y = 0.6(-3(-9 + x) + x(-9 + x))
y = 0.6((-9 * -3 + x * -3) + x(-9 + x))
y = 0.6((27 + -3x) + x(-9 + x))
y = 0.6(27 + -3x + (-9 * x + x * x))
y = 0.6(27 + -3x + (-9x + x2))

Combine like terms: -3x + -9x = -12x
y = 0.6(27 + -12x + x2)
y = (27 * 0.6 + -12x * 0.6 + x2 * 0.6)
y = (16.2 + -7.2x + 0.6x2)

Solving
y = 16.2 + -7.2x + 0.6x2

Solving for variable 'y'.

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