Question 1096681: x2 + y2 − 10x − 18 = 0
find the circle and radius of the given equation
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
x^2 + y^2 - 10x - 18 = 0
x^2 - 10x + y^2 = 18
Complete the square
x^2 - 10x + 25 + y^2 = 18 + 25 = 43
(x-5)^2 + y^2 = 43
Center (5,0)
r = sqrt(43)
