From the information given the circle centre is (-4,3).

Since no sign is given with '4' , it is assumed it is positive.

The '= 4' is radius squared (Pythagoras).

So the whole equation becomes

(x --4)^2 + (y - 3)^2= 4 = 2^2 =>

( x + 4)^2 + ( y - 3)^2 = 2^2 (Note the Pythagorean equation).

Multiply out

x^2 + 8x + 16 + y^2 - 6y + 9 = 4

Collect terms

x^2 + y^2 + 8x - 6y + 21 = 0

The equation of the given circle.

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

What is the relationship between the area of a circle and its radius squared?

Relationship between circle are and radius squa0red is A(Area) = pi r^2(radius squared). pi is the constant of proportionality for ALL circles . It has a value of 3.141592.....
