Solution for 4*y^2-5*y+3=0 equation:


Simplifying
4y2 + -5y + 3 = 0

Reorder the terms:
3 + -5y + 4y2 = 0

Solving
3 + -5y + 4y2 = 0

Solving for variable 'y'.

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

Divide each side by '4'.
0.75 + -1.25y + y2 = 0

Move the constant term to the right:

Add '-0.75' to each side of the equation.
0.75 + -1.25y + -0.75 + y2 = 0 + -0.75

Reorder the terms:
0.75 + -0.75 + -1.25y + y2 = 0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + -1.25y + y2 = 0 + -0.75
-1.25y + y2 = 0 + -0.75

Combine like terms: 0 + -0.75 = -0.75
-1.25y + y2 = -0.75

The y term is -1.25y.  Take half its coefficient (-0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
-1.25y + 0.390625 + y2 = -0.75 + 0.390625

Reorder the terms:
0.390625 + -1.25y + y2 = -0.75 + 0.390625

Combine like terms: -0.75 + 0.390625 = -0.359375
0.390625 + -1.25y + y2 = -0.359375

Factor a perfect square on the left side:
(y + -0.625)(y + -0.625) = -0.359375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
