This type of expression is what we call a "difference of squares". This occurs whenever a perfect square is subtracted from another perfect square. It can be factored out to:
(x + y)(x - y)
To see why that is, try multiplying those two factors back together:
(x + y)(x - y)
= x(x - y) + y(x - y)
= x2 - xy + yx - y2
= x2 - xy + xy - y2
= x2 - y2

The circle is centered at the origin and the length of its radius is 8 What is the circle's equation?
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
What is the formula to calculate the slope?
It's m = y2 - y1/ x2- x1 It's m equals y2 minus y1 over x2 minus x1
X2 plus y2 equals 100 what is the lengrth of the circles radius?
X2 + y2 = 100 = r2 r = 10
What are the factors of x2 - y4?
-2
Is equation is x2 plus y2 equals 1 what is the circles radius?
Proper form first. X2 + Y2 = 1 Y2 = 1 - X2 Y = (+/-) sqrt(1 - X2) -------------------------- zero out the X Y = (+/-) sqrt(1 - 02) Y = 1 ----------------the radius of this circle
How do you factor x6 - y6?
(x - y)(x + y)(x2 - xy + y2)(x2 + xy + y2)
Who can factor x2 - y2 plus 4y - 4?
x2 -y2 +4y-4=(x+y)(x-y)+4y-4
How do you factor x2-y2?
x2-y2=(x-y)(x+y) which is a well known identity.
How do you factor x2 minus y2?
(x - y)(x + y)
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)
How do you factor x3 plus y3?
(x2 - xy + y2)(x + y)
What is the expansion for x2 plus y2?
Well, darling, the expansion for x^2 + y^2 is simply x^2 + y^2. That's all there is to it, no fancy footwork needed. Just keep it simple and enjoy the math ride, honey.
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 factor of x2-y2 equals 16?
(x + y)(x - y) = 16
How do you factor 16x2-x2y4?
-x2(y - 2)(y + 2)(y2 + 4)
