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


Simplifying
5y2 + -4y + 5 = 0

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

Solving
5 + -4y + 5y2 = 0

Solving for variable 'y'.

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

Divide each side by '5'.
1 + -0.8y + y2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -0.8y + -1 + y2 = 0 + -1

Reorder the terms:
1 + -1 + -0.8y + y2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -0.8y + y2 = 0 + -1
-0.8y + y2 = 0 + -1

Combine like terms: 0 + -1 = -1
-0.8y + y2 = -1

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 = -1 + 0.16

Reorder the terms:
0.16 + -0.8y + y2 = -1 + 0.16

Combine like terms: -1 + 0.16 = -0.84
0.16 + -0.8y + y2 = -0.84

Factor a perfect square on the left side:
(y + -0.4)(y + -0.4) = -0.84

Can't calculate square root of the right side.

The solution to this equation could not be determined.
