Fool's problems of the day, Today's problems are based on standard analytic geometry, $$(1)$$ Find the center of the conic section $$13x^2-18xy+37y^2+2x+14y-2=0$$ [ Solved by @Mani_Jha and @.Sam. ] $$(2)$$ Prove that if the circles $$x^2+y^2+2g_1x+2f_1y+c_1 =0$$ and $$x^2+y^2+2g_2x+2f_2y+c_2 =0$$ are orthogonal then $$2(g_1g_2 +f_1f_2) = c_1+c_2$$ [Solved by @Ishaan94]
