y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
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

x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
The expression Y-2 is 1/Y2. The reciprocal of 1/Y2 is Y2.
y2 + y2 = 2y2
(y-6)(y-4) y x y = y2 y x -4 = -4y y x -6 = -6y -4 x -6 = 24 y2 - 4y - 6y + 24 y2 - 10y + 24
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
its appropriate for anyone. Y7 or rated G
y2
Yes. If you multiply X + iY by X - iY you get X2 + Y2. The imaginary parts cancel out.
4x-y2 = 2
Using the (surprise, surprise) "point-slope formula". The slope of a line is m = (y2 - y1)/(x2 - x1). If we let y2 and x2 be the variables x and y and multiply by y, we get y - y1 = m(x - x1).
88 + 5y - y2 66 - 3y + y2 Subtract: 22 + 8y -2y2
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
It is: y2
