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^2)/4+(y^2)/4 =25

\frac{x ^{2}}{4} + \frac{y ^{2}}{4} = 25

x^2+y^2-8x-2y+7=0

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

(x-(-3))^2+(y-(-2))^2=8^2

(x - (- 3))^{2} + (y - (- 2))^{2} = 8^{2}

(a+bi)*(a-bi)=1

(a + bi) \cdot (a - bi) = 1

x^2+y^2+8x+2y+4=0

x^{2} + y^{2} + 8 x + 2 y + 4 = 0
