(x-100)(x+1)=y

Solution for (x-100)(x+1)=y equation:

Simplifying
(x + -100)(x + 1) = y

Reorder the terms:
(-100 + x)(x + 1) = y

Reorder the terms:
(-100 + x)(1 + x) = y

Multiply (-100 + x) * (1 + x)
(-100(1 + x) + x(1 + x)) = y
((1 * -100 + x * -100) + x(1 + x)) = y
((-100 + -100x) + x(1 + x)) = y
(-100 + -100x + (1 * x + x * x)) = y
(-100 + -100x + (1x + x2)) = y

Combine like terms: -100x + 1x = -99x
(-100 + -99x + x2) = y

Solving
-100 + -99x + x2 = y

Solving for variable 'x'.

Combine like terms: y + -1y = 0
-100 + -99x + x2 + -1y = 0
