y=-(2x-5)(x+6)

Solution for y=-(2x-5)(x+6) equation:

Simplifying
y = -1(2x + -5)(x + 6)

Reorder the terms:
y = -1(-5 + 2x)(x + 6)

Reorder the terms:
y = -1(-5 + 2x)(6 + x)

Multiply (-5 + 2x) * (6 + x)
y = -1(-5(6 + x) + 2x * (6 + x))
y = -1((6 * -5 + x * -5) + 2x * (6 + x))
y = -1((-30 + -5x) + 2x * (6 + x))
y = -1(-30 + -5x + (6 * 2x + x * 2x))
y = -1(-30 + -5x + (12x + 2x2))

Combine like terms: -5x + 12x = 7x
y = -1(-30 + 7x + 2x2)
y = (-30 * -1 + 7x * -1 + 2x2 * -1)
y = (30 + -7x + -2x2)

Solving
y = 30 + -7x + -2x2

Solving for variable 'y'.

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