Solution for y=-0.5(x-10)(x+14) equation: 


Simplifying
y = -0.5(x + -10)(x + 14)

Reorder the terms:
y = -0.5(-10 + x)(x + 14)

Reorder the terms:
y = -0.5(-10 + x)(14 + x)

Multiply (-10 + x) * (14 + x)
y = -0.5(-10(14 + x) + x(14 + x))
y = -0.5((14 * -10 + x * -10) + x(14 + x))
y = -0.5((-140 + -10x) + x(14 + x))
y = -0.5(-140 + -10x + (14 * x + x * x))
y = -0.5(-140 + -10x + (14x + x2))

Combine like terms: -10x + 14x = 4x
y = -0.5(-140 + 4x + x2)
y = (-140 * -0.5 + 4x * -0.5 + x2 * -0.5)
y = (70 + -2x + -0.5x2)

Solving
y = 70 + -2x + -0.5x2

Solving for variable 'y'.

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

Simplifying
y = 70 + -2x + -0.5x2
