A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Find the radius of a circle with the equation x2 plus y2 equals 16?

x2 +y2 = R2 =16 = radius 2 R = 4


What is the radius for a circle whose equation is x2 plus y2 16?

I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.


Find the center and radius of a circle with equation X2 plus y2 plus x equals 0?

x2 + y2 - 5y + 4 = 0 x2 + y2 - 5y = - 4 x2 + y2 - 5y + 25/4 = - 4 + 25/4 = 9/4 x2 + (y - 5/2)2 = (3/2)2 Centre = (0, 5/2) and radius = 3/2


Which choice shows y2 in isolated form 4x2 plus 25y2 equals 100?

The one which says: y2 = 4 - 4/25 x2


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.


Who can factor x2 - y2 plus 4y - 4?

x2 -y2 +4y-4=(x+y)(x-y)+4y-4

If xy equals x2 plus y2 plus 2xy?

If:xy = x2 + y2 + 2xyThen:x2 + xy + y2 = 0Do you want to solve it for x?x2 + xy + (y/2)2 = (y/2)2 - y2(x + y/2)2 = y2/4 - y2x + y/2 = ± √(-3y2/4)x = -y/2 ± y√(-3) / 2x = (-y ± yi√3) / 2
