Solution for 4v^2+3v=-10 equation:


Simplifying
4v2 + 3v = -10

Reorder the terms:
3v + 4v2 = -10

Solving
3v + 4v2 = -10

Solving for variable 'v'.

Reorder the terms:
10 + 3v + 4v2 = -10 + 10

Combine like terms: -10 + 10 = 0
10 + 3v + 4v2 = 0

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

Divide each side by '4'.
2.5 + 0.75v + v2 = 0

Move the constant term to the right:

Add '-2.5' to each side of the equation.
2.5 + 0.75v + -2.5 + v2 = 0 + -2.5

Reorder the terms:
2.5 + -2.5 + 0.75v + v2 = 0 + -2.5

Combine like terms: 2.5 + -2.5 = 0.0
0.0 + 0.75v + v2 = 0 + -2.5
0.75v + v2 = 0 + -2.5

Combine like terms: 0 + -2.5 = -2.5
0.75v + v2 = -2.5

The v term is 0.75v.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75v + 0.140625 + v2 = -2.5 + 0.140625

Reorder the terms:
0.140625 + 0.75v + v2 = -2.5 + 0.140625

Combine like terms: -2.5 + 0.140625 = -2.359375
0.140625 + 0.75v + v2 = -2.359375

Factor a perfect square on the left side:
(v + 0.375)(v + 0.375) = -2.359375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
