Convert x2 plus y2 equals 2x?

Answer 1

What do you want to convert it to?

x2 + y2 = 2x

If you want to solve for y:

x2 + y2 = 2x

∴ y2 = 2x - x2

∴ y = (2x - x2)1/2

If you want to solve for x:

x2 + y2 = 2x

∴ x2 - 2x = -y2

∴ x2 - 2x + 1 = 1 - y2

∴ (x - 1)2 = 1 - y2

∴ x - 1 = ±(1 - y2)1/2

∴ x = 1 ± (1 - y2)1/2
