x^2+y^2+2x-8y-8=0

Lösung

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

Lösung

(a, b) = (- 1, 4), r = 5

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 4)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (- 1, 4), r = 5

(x-4)^{(2)}+(y-7)^{(2)}=4

(x - 4)^{(2)} + (y - 7)^{(2)} = 4

4 x^{2} - 8 \geq - 4 y^{2}

x^{2} + y^{2} - 4 x + 2 = 0

(a + b) 2 = a^{2} + b^{2}

x^2-10x+25+y^2-8y+16=64

x^{2} - 10 x + 25 + y^{2} - 8 y + 16 = 64
