Answer:
Solve for p:
p^2 (-p^2 + h^2) = h^2 x^2
Expand out terms of the left hand side:
-p^4 + h^2 p^2 = h^2 x^2
Subtract h^2 x^2 from both sides:
h^2 p^2 - p^4 - h^2 x^2 = 0
Substitute y = p^2:
-h^2 x^2 + h^2 y - y^2 = 0
Multiply both sides by -1:
h^2 x^2 - h^2 y + y^2 = 0
Subtract h^2 x^2 from both sides:
y^2 - h^2 y = -h^2 x^2
Add h^4/4 to both sides:
y^2 - h^2 y + h^4/4 = -h^2 x^2 + h^4/4
Write the both sides as a square:
(y - h^2/2)^2 = 1/4 h^2 (-2 x + h) (2 x + h)
Take the square root of both sides:
y - h^2/2 = 1/2 sqrt(h^2 (-2 x + h) (2 x + h)) or y - h^2/2 = -1/2 sqrt(h^2 (-2 x + h) (2 x + h))
Add h^2/2 to both sides:
y = h^2/2 + 1/2 sqrt(h^2 (-2 x + h) (2 x + h)) or y - h^2/2 = -1/2 sqrt(h^2 (-2 x + h) (2 x + h))
Substitute back for y = p^2:
p^2 = h^2/2 + 1/2 sqrt(h^2 (-2 x + h) (2 x + h)) or y - h^2/2 = -1/2 sqrt(h^2 (-2 x + h) (2 x + h))
Take the square root of both sides:
p = sqrt(h^2/2 + 1/2 sqrt(h^2 (-2 x + h) (2 x + h))) or p = -sqrt(h^2/2 + 1/2 sqrt(h^2 (-2 x + h) (2 x + h))) or y - h^2/2 = -1/2 sqrt(h^2 (-2 x + h) (2 x + h))
h^2 (-2 x + h) (2 x + h) = -4 h^2 x^2 + h^4:
p = sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 + 1/2 sqrt(h^2 (-2 x + h) (2 x + h))) or y - h^2/2 = -1/2 sqrt(h^2 (-2 x + h) (2 x + h))
h^2 (-2 x + h) (2 x + h) = -4 h^2 x^2 + h^4:
p = sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or y - h^2/2 = -1/2 sqrt(h^2 (-2 x + h) (2 x + h))
Add h^2/2 to both sides:
p = sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or y = h^2/2 - 1/2 sqrt(h^2 (-2 x + h) (2 x + h))
Substitute back for y = p^2:
p = sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p^2 = h^2/2 - 1/2 sqrt(h^2 (-2 x + h) (2 x + h))
Take the square root of both sides:
p = sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = sqrt(h^2/2 - 1/2 sqrt(h^2 (-2 x + h) (2 x + h))) or p = -sqrt(h^2/2 - 1/2 sqrt(h^2 (-2 x + h) (2 x + h)))
h^2 (-2 x + h) (2 x + h) = -4 h^2 x^2 + h^4:
p = sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 + 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = sqrt(h^2/2 - 1/2 sqrt(-4 h^2 x^2 + h^4)) or p = -sqrt(h^2/2 - 1/2 sqrt(h^2 (-2 x + h) (2 x + h)))
h^2 (-2 x + h) (2 x + h) = -4 h^2 x^2 + h^4:
