Solution for y=.2x(x-5)(x-9.1) equation: 


Simplifying
y = 0.2x(x + -5)(x + -9.1)

Reorder the terms:
y = 0.2x(-5 + x)(x + -9.1)

Reorder the terms:
y = 0.2x(-5 + x)(-9.1 + x)

Multiply (-5 + x) * (-9.1 + x)
y = 0.2x(-5(-9.1 + x) + x(-9.1 + x))
y = 0.2x((-9.1 * -5 + x * -5) + x(-9.1 + x))
y = 0.2x((45.5 + -5x) + x(-9.1 + x))
y = 0.2x(45.5 + -5x + (-9.1 * x + x * x))
y = 0.2x(45.5 + -5x + (-9.1x + x2))

Combine like terms: -5x + -9.1x = -14.1x
y = 0.2x(45.5 + -14.1x + x2)
y = (45.5 * 0.2x + -14.1x * 0.2x + x2 * 0.2x)
y = (9.1x + -2.82x2 + 0.2x3)

Solving
y = 9.1x + -2.82x2 + 0.2x3

Solving for variable 'y'.

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

Simplifying
y = 9.1x + -2.82x2 + 0.2x3
