If it's not what You are looking for type in the equation solver your own equation and let us solve it.

v2=-84

We move all terms to the left:

v2-(-84)=0

We add all the numbers together, and all the variables

v^2+84=0

a = 1; b = 0; c = +84;

Δ = b^{2}-4ac

Δ = 0^{2}-4·1·84

Δ = -336

Delta is less than zero, so there is no solution for the equation
