y=2(x+5)(x-1)

Solution for y=2(x+5)(x-1) equation:

Simplifying
y = 2(x + 5)(x + -1)

Reorder the terms:
y = 2(5 + x)(x + -1)

Reorder the terms:
y = 2(5 + x)(-1 + x)

Multiply (5 + x) * (-1 + x)
y = 2(5(-1 + x) + x(-1 + x))
y = 2((-1 * 5 + x * 5) + x(-1 + x))
y = 2((-5 + 5x) + x(-1 + x))
y = 2(-5 + 5x + (-1 * x + x * x))
y = 2(-5 + 5x + (-1x + x2))

Combine like terms: 5x + -1x = 4x
y = 2(-5 + 4x + x2)
y = (-5 * 2 + 4x * 2 + x2 * 2)
y = (-10 + 8x + 2x2)

Solving
y = -10 + 8x + 2x2

Solving for variable 'y'.

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