Will mark brainliest which choice shows the first step in finding the center of the circle by completing the square? a complete the quadratics b factor the quadratic c group like terms d identify the center and radius

Suppose we have a generic equation of the form:
 

 1) The first thing you must do to complete squares is to group similar terms of the form:


 2) The second step is to complete the squares.

 3) The third step is factor the quadratic equation

 4) The fourth step is to identify the center and the radius

 
 the first step in finding the center of the circle by completing the square is:
 C group like terms
