Can someone please help me find the x-intercepts and y-intecepts of this equation. I have the radius, and center but I can't seem to get the intercepts.

x^2+y^2=16x-18y+145=25

Please show work. Thanks!!

sorry that should be

x^2+y^2+16x-18y+145=25

Been up to long working on this. Again I am sorry!!

regroup things a bit to get

x^2+16x+64 + y^2-18y+81 = 25

(x+8)^2 + (y-9)^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!
