x^2+y^2+2x=9

x^{2} + y^{2} + 2 x = 9

(a, b) = (- 1, 0), r = 10

Solution steps

x^{2} + y^{2} + 2 x = 9

Rewrite

x^{2} + y^{2} + 2 x = 9

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 0)^{2} = (10)^{2}

Therefore the circle properties are:

(a, b) = (- 1, 0), r = 10

(x - 2)^{2} + (y - 0)^{2} = 2^{2}

x^{2} - 8 x + y^{2} - 7 y + 1 = 0

\frac{( x - 1 ) ^{2}}{4} + \frac{( y - 3 ) ^{2}}{4} = 1

(x + 4)^{2} + (y - 4)^{2} = 22

x^{2} + y^{2} - 3 x = 15 - 6 y
