Solution for 5y^2-4y+10y+17=0 equation:


Simplifying
5y2 + -4y + 10y + 17 = 0

Reorder the terms:
17 + -4y + 10y + 5y2 = 0

Combine like terms: -4y + 10y = 6y
17 + 6y + 5y2 = 0

Solving
17 + 6y + 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'.
3.4 + 1.2y + y2 = 0

Move the constant term to the right:

Add '-3.4' to each side of the equation.
3.4 + 1.2y + -3.4 + y2 = 0 + -3.4

Reorder the terms:
3.4 + -3.4 + 1.2y + y2 = 0 + -3.4

Combine like terms: 3.4 + -3.4 = 0.0
0.0 + 1.2y + y2 = 0 + -3.4
1.2y + y2 = 0 + -3.4

Combine like terms: 0 + -3.4 = -3.4
1.2y + y2 = -3.4

The y term is 1.2y.  Take half its coefficient (0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
1.2y + 0.36 + y2 = -3.4 + 0.36

Reorder the terms:
0.36 + 1.2y + y2 = -3.4 + 0.36

Combine like terms: -3.4 + 0.36 = -3.04
0.36 + 1.2y + y2 = -3.04

Factor a perfect square on the left side:
(y + 0.6)(y + 0.6) = -3.04

Can't calculate square root of the right side.

The solution to this equation could not be determined.
