Solution for (4v^2)+20v+39=0 equation:


Simplifying
(4v2) + 20v + 39 = 0

Reorder the terms:
39 + 20v + (4v2) = 0

Solving
39 + 20v + (4v2) = 0

Solving for variable 'v'.

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

Divide each side by '4'.
9.75 + 5v + v2 = 0

Move the constant term to the right:

Add '-9.75' to each side of the equation.
9.75 + 5v + -9.75 + v2 = 0 + -9.75

Reorder the terms:
9.75 + -9.75 + 5v + v2 = 0 + -9.75

Combine like terms: 9.75 + -9.75 = 0.00
0.00 + 5v + v2 = 0 + -9.75
5v + v2 = 0 + -9.75

Combine like terms: 0 + -9.75 = -9.75
5v + v2 = -9.75

The v term is 5v.  Take half its coefficient (2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
5v + 6.25 + v2 = -9.75 + 6.25

Reorder the terms:
6.25 + 5v + v2 = -9.75 + 6.25

Combine like terms: -9.75 + 6.25 = -3.5
6.25 + 5v + v2 = -3.5

Factor a perfect square on the left side:
((v) + 2.5)((v) + 2.5) = -3.5

Can't calculate square root of the right side.

The solution to this equation could not be determined.
