Solution for (5y^2-2y-1)-(-y-2-3y^2)= equation: 


Simplifying
(5y2 + -2y + -1) + -1(-1y + -2 + -3y2) = 0

Reorder the terms:
(-1 + -2y + 5y2) + -1(-1y + -2 + -3y2) = 0

Remove parenthesis around (-1 + -2y + 5y2)
-1 + -2y + 5y2 + -1(-1y + -2 + -3y2) = 0

Reorder the terms:
-1 + -2y + 5y2 + -1(-2 + -1y + -3y2) = 0
-1 + -2y + 5y2 + (-2 * -1 + -1y * -1 + -3y2 * -1) = 0
-1 + -2y + 5y2 + (2 + 1y + 3y2) = 0

-1 + 2 + -2y + 1y + 5y2 + 3y2 = 0

Combine like terms: -1 + 2 = 1
1 + -2y + 1y + 5y2 + 3y2 = 0

Combine like terms: -2y + 1y = -1y
1 + -1y + 5y2 + 3y2 = 0

Combine like terms: 5y2 + 3y2 = 8y2
1 + -1y + 8y2 = 0

Solving
1 + -1y + 8y2 = 0

Solving for variable 'y'.

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

Divide each side by '8'.
0.125 + -0.125y + y2 = 0

Move the constant term to the right:

Add '-0.125' to each side of the equation.
0.125 + -0.125y + -0.125 + y2 = 0 + -0.125

Reorder the terms:
0.125 + -0.125 + -0.125y + y2 = 0 + -0.125

Combine like terms: 0.125 + -0.125 = 0.000
0.000 + -0.125y + y2 = 0 + -0.125
-0.125y + y2 = 0 + -0.125

Combine like terms: 0 + -0.125 = -0.125
-0.125y + y2 = -0.125

The y term is -0.125y.  Take half its coefficient (-0.0625).
Square it (0.00390625) and add it to both sides.

Add '0.00390625' to each side of the equation.
-0.125y + 0.00390625 + y2 = -0.125 + 0.00390625

Reorder the terms:
0.00390625 + -0.125y + y2 = -0.125 + 0.00390625

Combine like terms: -0.125 + 0.00390625 = -0.12109375
0.00390625 + -0.125y + y2 = -0.12109375

Factor a perfect square on the left side:
(y + -0.0625)(y + -0.0625) = -0.12109375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
