Answer:
The center is (0,0) and the radius is 3
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2+(y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x-0)^2+(y-0)^2 = 3^2
The center is (0,0) and the radius is 3
Answer:
x^2 -3x +15
Step-by-step explanation:
7x^2 +6x -9x - 6x^2 +15
Combine like terms
