What is the result of isolating y2 in the equation below (x plus 4) plus y2 22?
y2=-x2-8x+6
Who can factor x2 - y2 plus 4y - 4?
x2 -y2 +4y-4=(x+y)(x-y)+4y-4
Factorise x2 minus y2 plus 9x minus 9y?
x2 - y2 + 9x - 9y =(x2 + 9x) - (y2 + 9y) =x(x + 9) - y(y + 9)================================Another way to go after it:x2 - y2 + 9x - 9y =(x2 - y2) + 9x - 9y =(x + y) (x - y) + 9 (x - y) =(x + y + 9) (x - y)
What is the answer to x squared plus y squared equals 25?
X2+y2=25 (x-8)2+y2 =41
How do you factor x6 - y6?
(x - y)(x + y)(x2 - xy + y2)(x2 + xy + y2)
What is the answer to (x plus y)2 x2 plus y2?
X2+y2=25 (x-8)2+y2 =41
Equation of director circle of the circle x2 plus y2 equals r2 is?
x2 + y2 = 2r2
Convert x2 plus y2 equals 2x?
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
What is the result of isolating y2 in the equation below (x plus 4) plus y2 22?
y2=-x2-8x+6

What the radius for a circle with the equation x2 plus y2 equals 25?
5. A circle with centre (0,0) has equation: x2 + y2 = radius2 With: x2 + y2 = 25 = 52 The radius is 5.
How do you convert x2 plus y2 equals z to standard form for y?
X2 + Y2 = Z subtract X2 from each side Y2 = - X2 + Z take square root each side Y = sqrt(- X2 + Z) =============
X2 y2 equals 121 what is the radius?
If this is the equation of a circle, the answer is 11, except that there needs to be a plus sigb between the x2 and the y2
How do you factor 4-y²?
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)
