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


Simplifying
v2 + 3v = -5

Reorder the terms:
3v + v2 = -5

Solving
3v + v2 = -5

Solving for variable 'v'.

Reorder the terms:
5 + 3v + v2 = -5 + 5

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

Begin completing the square.

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + 3v + -5 + v2 = 0 + -5

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

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

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

The v term is 3v.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3v + 2.25 + v2 = -5 + 2.25

Reorder the terms:
2.25 + 3v + v2 = -5 + 2.25

Combine like terms: -5 + 2.25 = -2.75
2.25 + 3v + v2 = -2.75

Factor a perfect square on the left side:
(v + 1.5)(v + 1.5) = -2.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
