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.
1 m2 = 1.196 y2 approx.
y2 + y2 = 2y2
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
y2
4x-y2 = 2
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

y2 there will me many solutions
4 - y2 can be written as 22 - y2. This has become of the form of x2 - y2.Expansion for x2 - y2 is (x+y)(x-y).So, 4 - y2 = 22 - y2 = (2+y)(2-y)
x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
There is no expansion for x2 + y2
