Complete the square
v^2 + 2v - 28 = -4
~~~~~~~~~~~~~~~~~

Hey, this is incorrect formulation.
The correct formulation is "Solve the equation by completing the square".

v%5E2+%2B+2v+-+28 = -4  --->

%28v%5E2+%2B+2v+%2B+1%29+-1+-28 = -4  --->

{{(v+1)^2 - 29}}} = -4  --->

%28v%2B1%29%5E2 = 29-4  --->

%28v%2B1%29%5E2 = 25  --->

v+1 = +/- 5  ---> Two solutions: v = -1 + 5 = 4  and  v = -1 + 5 = 4.

Answer.  There are two solutions: v = -1 + 5 = 4  and  v = -1 - 5 = -6.
