y=2(-x+100)(x+60)

Solution for y=2(-x+100)(x+60) equation:

Simplifying
y = 2(-1x + 100)(x + 60)

Reorder the terms:
y = 2(100 + -1x)(x + 60)

Reorder the terms:
y = 2(100 + -1x)(60 + x)

Multiply (100 + -1x) * (60 + x)
y = 2(100(60 + x) + -1x * (60 + x))
y = 2((60 * 100 + x * 100) + -1x * (60 + x))
y = 2((6000 + 100x) + -1x * (60 + x))
y = 2(6000 + 100x + (60 * -1x + x * -1x))
y = 2(6000 + 100x + (-60x + -1x2))

Combine like terms: 100x + -60x = 40x
y = 2(6000 + 40x + -1x2)
y = (6000 * 2 + 40x * 2 + -1x2 * 2)
y = (12000 + 80x + -2x2)

Solving
y = 12000 + 80x + -2x2

Solving for variable 'y'.

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

Simplifying
y = 12000 + 80x + -2x2
