Can someone please help me find the xintercepts and yintecepts of this equation. I have the radius, and center but I can't seem to get the intercepts.
x^2+y^2=16x18y+145=25
Please show work. Thanks!!

sorry that should be
x^2+y^2+16x18y+145=25
Been up to long working on this. Again I am sorry!!

regroup things a bit to get
x^2+16x+64 + y^218y+81 = 25
(x+8)^2 + (y9)^2 = 25
no wonder you can't find the intercepts. This is a circle at (8,9) with radius 5. It's too far away from the axes to intercept them!
