Shouldn't there be a + sign between the 2 and the 3? What you have written is not the equation of a circle.

divide everybody by 3
(x5)^2 + y^2 = 4
centre : (5,0), radius 2
clearly the circle can't reach the yaxis,
(let x= 0, > 75 + 3y^2 = 12
3y^2 =  .... , not possible)
for the xintercepts , let y = 0
3(x5)^2 = 12
(x5)^2 = 4
x5 = ± 2
x = 7 or x = 3
