Beliebt Geometry >

(x^2+4x)+(y^2-10y)=-4

Lösung

(x^{2} + 4 x) + (y^{2} - 10 y) = - 4

Lösung

(a, b) = (- 2, 5), r = 5

Schritte zur Lösung

x^{2} + 4 x + (y^{2} - 10 y) = - 4

Rewrite

x^{2} + 4 x + (y^{2} - 10 y) = - 4

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (- 2, 5), r = 5

(4(x+5/2)^2)/(45)+(4(y-2)^2)/(45)=1

\frac{4 ( x + \frac{5}{2} ) ^{2}}{45} + \frac{4 ( y - 2 ) ^{2}}{45} = 1

x^2-18x+29+y^2=0

x^{2} - 18 x + 29 + y^{2} = 0

3 x^{2} > 12 - 3 y^{2}

x^2+y^2-16x-18y+109=0

x^{2} + y^{2} - 16 x - 18 y + 109 = 0

(x-4)^2+(y-5)^2=9

(x - 4)^{2} + (y - 5)^{2} = 9
