Solving
-1y + 5y2 = -4 + 3y

Solving for variable 'y'.

Reorder the terms:
4 + -1y + -3y + 5y2 = -4 + 3y + 4 + -3y

Combine like terms: -1y + -3y = -4y
4 + -4y + 5y2 = -4 + 3y + 4 + -3y

Reorder the terms:
4 + -4y + 5y2 = -4 + 4 + 3y + -3y

Combine like terms: -4 + 4 = 0
4 + -4y + 5y2 = 0 + 3y + -3y
4 + -4y + 5y2 = 3y + -3y

Combine like terms: 3y + -3y = 0
4 + -4y + 5y2 = 0

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

Divide each side by '5'.
0.8 + -0.8y + y2 = 0

Move the constant term to the right:

Add '-0.8' to each side of the equation.
0.8 + -0.8y + -0.8 + y2 = 0 + -0.8

Reorder the terms:
0.8 + -0.8 + -0.8y + y2 = 0 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0
0.0 + -0.8y + y2 = 0 + -0.8
-0.8y + y2 = 0 + -0.8

Combine like terms: 0 + -0.8 = -0.8
-0.8y + y2 = -0.8

The y term is -0.8y.  Take half its coefficient (-0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
-0.8y + 0.16 + y2 = -0.8 + 0.16

Reorder the terms:
0.16 + -0.8y + y2 = -0.8 + 0.16

Combine like terms: -0.8 + 0.16 = -0.64
0.16 + -0.8y + y2 = -0.64

Factor a perfect square on the left side:
(y + -0.4)(y + -0.4) = -0.64

Can't calculate square root of the right side.

The solution to this equation could not be determined.
