y = x2 + 2mx + n

complete the square

y + m2 = x2 + 2mx + m2 + n = (x + m)2 + n

(x + m)2 = y + m2 - n

x + m = √(y + m2 - n)

x = -m + √(y + m2 - n) Wiki User

### Xsquared - v equals wsquared what is X how did you work this out?

It is not possible to solve for a value of X since there are three unknowns, X, v and W and only one equation. All that can be done is to make x the subject of the equation - that is, to express X in terms of the other two variables. X2 - v = W2 X2 = W2 + v X = +/- sqrt(W2 + v)
