$x^{2} + y^{2} = 49$

Step 1

Divide each term by $49$ to make the right side equal to one.

$\frac{x^{2}}{49} + \frac{y^{2}}{49} = \frac{49}{49}$

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 $1$ .

$\frac{x^{2}}{49} + \frac{y^{2}}{49} = 1$
