How do you rearrange v squared equals b squared bracket a squared - x squared bracket to make x the subject?

Answer 1

v2 = b2 (a2 - x2)

Divide each side by b2 :

v2/b2 = a2 - x2

Subtract a2 from each side:

v2/b2 - a2 = -x2

Multiply each side by -1 :

x2 = a2 - v2/b2

Take the square root of each side:

x = ± sqrt ( a2 - v2/b2 )
