Solution for Y=-1(x-10)(x-20) equation: 


Simplifying
Y = -1(x + -10)(x + -20)

Reorder the terms:
Y = -1(-10 + x)(x + -20)

Reorder the terms:
Y = -1(-10 + x)(-20 + x)

Multiply (-10 + x) * (-20 + x)
Y = -1(-10(-20 + x) + x(-20 + x))
Y = -1((-20 * -10 + x * -10) + x(-20 + x))
Y = -1((200 + -10x) + x(-20 + x))
Y = -1(200 + -10x + (-20 * x + x * x))
Y = -1(200 + -10x + (-20x + x2))

Combine like terms: -10x + -20x = -30x
Y = -1(200 + -30x + x2)
Y = (200 * -1 + -30x * -1 + x2 * -1)
Y = (-200 + 30x + -1x2)

Solving
Y = -200 + 30x + -1x2

Solving for variable 'Y'.
