-4x^2+7y^2+8x+42y+31=0

Lösung

- 4 x^{2} + 7 y^{2} + 8 x + 42 y + 31 = 0

Lösung

(h, k) = (1, - 3), a = 2, b = 7

Schritte zur Lösung

- 4 x^{2} + 7 y^{2} + 8 x + 42 y + 31 = 0

Rewrite

- 4 x^{2} + 7 y^{2} + 8 x + 42 y + 31 = 0

in the form of a standard hyperbola equation

\frac{( y - ( - 3 ) ) ^{2}}{2 ^{2}} - \frac{( x - 1 ) ^{2}}{( 7 ) ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (1, - 3), a = 2, b = 7
