Solution for (5v^2-2v)+(3-v^2)=0 equation:


Simplifying
(5v2 + -2v) + (3 + -1v2) = 0

Reorder the terms:
(-2v + 5v2) + (3 + -1v2) = 0

Remove parenthesis around (-2v + 5v2)
-2v + 5v2 + (3 + -1v2) = 0

Remove parenthesis around (3 + -1v2)
-2v + 5v2 + 3 + -1v2 = 0

Reorder the terms:
3 + -2v + 5v2 + -1v2 = 0

Combine like terms: 5v2 + -1v2 = 4v2
3 + -2v + 4v2 = 0

Solving
3 + -2v + 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'.
0.75 + -0.5v + v2 = 0

Move the constant term to the right:

Add '-0.75' to each side of the equation.
0.75 + -0.5v + -0.75 + v2 = 0 + -0.75

Reorder the terms:
0.75 + -0.75 + -0.5v + v2 = 0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + -0.5v + v2 = 0 + -0.75
-0.5v + v2 = 0 + -0.75

Combine like terms: 0 + -0.75 = -0.75
-0.5v + v2 = -0.75

The v term is -0.5v.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5v + 0.0625 + v2 = -0.75 + 0.0625

Reorder the terms:
0.0625 + -0.5v + v2 = -0.75 + 0.0625

Combine like terms: -0.75 + 0.0625 = -0.6875
0.0625 + -0.5v + v2 = -0.6875

Factor a perfect square on the left side:
(v + -0.25)(v + -0.25) = -0.6875

Can't calculate square root of the right side.

The solution to this equation could not be determined.
