Answer:

g =
(p^2-V^2)/(2h)

Explanation:

assuming I have your statement correctly interpreted.

V =
√(p^2-2gh) ( square both sides to clear the radical )

V² = p² - 2gh ( subtract p² from both sides )

V² - p² = - 2gh ( isolate g by dividing both sides by - 2h )


(V^2-p^2)/(-2h) = g

multiply numerator/ denominator of left side by - 1

g =
(p^2-V^2)/(2h)
