Solution for v^2+7v+30=0 equation:


Simplifying
v2 + 7v + 30 = 0

Reorder the terms:
30 + 7v + v2 = 0

Solving
30 + 7v + v2 = 0

Solving for variable 'v'.

Begin completing the square.

Move the constant term to the right:

Add '-30' to each side of the equation.
30 + 7v + -30 + v2 = 0 + -30

Reorder the terms:
30 + -30 + 7v + v2 = 0 + -30

Combine like terms: 30 + -30 = 0
0 + 7v + v2 = 0 + -30
7v + v2 = 0 + -30

Combine like terms: 0 + -30 = -30
7v + v2 = -30

The v term is 7v.  Take half its coefficient (3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
7v + 12.25 + v2 = -30 + 12.25

Reorder the terms:
12.25 + 7v + v2 = -30 + 12.25

Combine like terms: -30 + 12.25 = -17.75
12.25 + 7v + v2 = -17.75

Factor a perfect square on the left side:
(v + 3.5)(v + 3.5) = -17.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
