How do you factor the polynomial y2-4y-32?
factor 4y - 32
How do you factor y squared plus 4y?
All you can do to factor that expression is to divide both terms by y: y2 + 4y = y(y + 4)
What is the expansion for x2 plus y2?
There is no expansion for x2 + y2
How do you factor x6 - y6?
(x - y)(x + y)(x2 - xy + y2)(x2 + xy + y2)
What is the result of isolating y2 in the equation below (x plus 4) plus y2 22?
y2=-x2-8x+6
What is the radius of x2 plus y2 - 10x plus 4y - 52 equals 0?
Complete the squares: x2 - 10x + 25 + y2 + 4y + 4 - 52 = 25 + 4 = 29 x2 - 10x + 25 + y2 + 4y + 4 = 52 + 29 = 81 So the radius is sqrt(81) = 9
How do you find the radius of the circle with the given equation of x2 plus y2-10x plus 4y plus 4 equals 0?
Given: x2 + y2 - 10x + 4y + 4 = 0 First, we'll move our constants to the right: x2 + y2 - 10x + 4y = -4 Then group terms with the same variables together: x2 - 10x + y2 + 4y = -4 Then complete the squares: x2 - 10x + 25 + y2 + 4y + 4 = -4 + 25 + 4 (x - 5)2 + (y + 2)2 = 25 And there we have it. This is an equation for a circle whose center point is at (5, -2), with a radius of √25, which equals 5.
How do you solve the equation. X2 plus y2 plus z2 - 4x plus 4y plus 2z plus 5 equals 0 x2 plus y2 plus z2 equals 4?

How do you factor the polynomial y2-4y-32?
factor 4y - 32
X 2 plus y 2 - 10x plus 4y - 52 equals 0?
x2 + y2 - 10x + 4y - 52 = 0 x2 - 10x + y2 + 4y = 52 Complete the square (x2 - 10x + 25) + (y2 + 4y + 4) = 52 + 25 + 4 (x - 5)2 + (y + 2)2 = 81 (x - 5)2 + (y - -2)2 = 92 This is the equation of a circle with center (5, -2), and radius 9.
How do you factor y squared plus 4y?
All you can do to factor that expression is to divide both terms by y: y2 + 4y = y(y + 4)
How do you factor x3 plus y3?
(x2 - xy + y2)(x + y)
What is the expansion for x2 plus y2?
There is no expansion for x2 + y2
How do you factor y2 plus 8y plus 16?
y2 + 8y + 16 = y2 + 4y + 4y + 16 = y(y + 4) + 4(y + 4) = (y + 4)(y + 4) or (y + 4)2
How do you factor x2-y2 plus 7x plus 7y?
(x - y + 7)(x + y)
What is the solution to x2 plus 2y-6x plus 8y-1 equals x2-y2 plus 4x-6y-1?
x2 + 2y - 6x + 8y - 1 = x2 - y2 + 4x + 6y - 1 y2 - 10x + 4y = 0 y(y+4) = 10x It cannot be solved completely because with two variables (x and y) you need two independent equations for a full solution.
What is the answer to (x plus y)2 x2 plus y2?
X2+y2=25 (x-8)2+y2 =41
