Examples

$27 x^{2} - 9 y^{2} = 81$

Step 1

Divide each term by

$81$ to make the right side equal to one.

$\frac{27 x^{2}}{81} - \frac{9 y^{2}}{81} = \frac{81}{81}$

Step 2

Simplify each term in the equation in order to set the right side equal to

$1$ . The standard form of an ellipse or hyperbola requires the right side of the equation be

$1$ .

$\frac{x^{2}}{3} - \frac{y^{2}}{9} = 1$
