Solution for y(40+-1y)=500 equation:


Simplifying
y(40 + -1y) = 500
(40 * y + -1y * y) = 500
(40y + -1y2) = 500

Solving
40y + -1y2 = 500

Solving for variable 'y'.

Reorder the terms:
-500 + 40y + -1y2 = 500 + -500

Combine like terms: 500 + -500 = 0
-500 + 40y + -1y2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
500 + -40y + y2 = 0

Move the constant term to the right:

Add '-500' to each side of the equation.
500 + -40y + -500 + y2 = 0 + -500

Reorder the terms:
500 + -500 + -40y + y2 = 0 + -500

Combine like terms: 500 + -500 = 0
0 + -40y + y2 = 0 + -500
-40y + y2 = 0 + -500

Combine like terms: 0 + -500 = -500
-40y + y2 = -500

The y term is -40y.  Take half its coefficient (-20).
Square it (400) and add it to both sides.

Add '400' to each side of the equation.
-40y + 400 + y2 = -500 + 400
