Solution for -2(6y-10)-y=-4y(y-5) equation:


Simplifying
-2(6y + -10) + -1y = -4y(y + -5)

Reorder the terms:
-2(-10 + 6y) + -1y = -4y(y + -5)
(-10 * -2 + 6y * -2) + -1y = -4y(y + -5)
(20 + -12y) + -1y = -4y(y + -5)

Combine like terms: -12y + -1y = -13y
20 + -13y = -4y(y + -5)

Reorder the terms:
20 + -13y = -4y(-5 + y)
20 + -13y = (-5 * -4y + y * -4y)
20 + -13y = (20y + -4y2)

Solving
20 + -13y = 20y + -4y2

Solving for variable 'y'.

Combine like terms: -13y + -20y = -33y
20 + -33y + 4y2 = 20y + -4y2 + -20y + 4y2

Reorder the terms:
20 + -33y + 4y2 = 20y + -20y + -4y2 + 4y2

Combine like terms: 20y + -20y = 0
20 + -33y + 4y2 = 0 + -4y2 + 4y2
20 + -33y + 4y2 = -4y2 + 4y2

Combine like terms: -4y2 + 4y2 = 0
20 + -33y + 4y2 = 0

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

Divide each side by '4'.
5 + -8.25y + y2 = 0

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -8.25y + -5 + y2 = 0 + -5

Reorder the terms:
5 + -5 + -8.25y + y2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -8.25y + y2 = 0 + -5
-8.25y + y2 = 0 + -5

Combine like terms: 0 + -5 = -5
-8.25y + y2 = -5

The y term is -8.25y.  Take half its coefficient (-4.125).
