Solution for 3y+1=-4y^2 equation:


Simplifying
3y + 1 = -4y2

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

Solving
1 + 3y = -4y2

Solving for variable 'y'.

Combine like terms: -4y2 + 4y2 = 0
1 + 3y + 4y2 = 0

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

Divide each side by '4'.
0.25 + 0.75y + y2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + 0.75y + -0.25 + y2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + 0.75y + y2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + 0.75y + y2 = 0 + -0.25
0.75y + y2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
0.75y + y2 = -0.25

The y term is 0.75y.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75y + 0.140625 + y2 = -0.25 + 0.140625

Reorder the terms:
0.140625 + 0.75y + y2 = -0.25 + 0.140625

Combine like terms: -0.25 + 0.140625 = -0.109375
0.140625 + 0.75y + y2 = -0.109375

Factor a perfect square on the left side:
(y + 0.375)(y + 0.375) = -0.109375

Can't calculate square root of the right side.
