Question

the equation of a circle can be changed from general form to standard form by doing which of the following? choose the correct answer below. a. solving for x b. squaring both sides c. completing the squares d. solving for y

Explanation:

Step1: Recall circle - form conversion

To convert the general form of the equation of a circle $x^{2}+y^{2}+Dx + Ey+F = 0$ to the standard form $(x - a)^{2}+(y - b)^{2}=r^{2}$, we use the method of completing the square for both the $x$ - terms and the $y$ - terms.

Answer:

C. completing the squares
