Solution for y=-(x+3)(x-8) equation: 


Simplifying
y = -1(x + 3)(x + -8)

Reorder the terms:
y = -1(3 + x)(x + -8)

Reorder the terms:
y = -1(3 + x)(-8 + x)

Multiply (3 + x) * (-8 + x)
y = -1(3(-8 + x) + x(-8 + x))
y = -1((-8 * 3 + x * 3) + x(-8 + x))
y = -1((-24 + 3x) + x(-8 + x))
y = -1(-24 + 3x + (-8 * x + x * x))
y = -1(-24 + 3x + (-8x + x2))

Combine like terms: 3x + -8x = -5x
y = -1(-24 + -5x + x2)
y = (-24 * -1 + -5x * -1 + x2 * -1)
y = (24 + 5x + -1x2)

Solving
y = 24 + 5x + -1x2

Solving for variable 'y'.
