Write the Given Equation in the Form $( x - h ) ^ { 2 } + ( y - k ) ^ { 2 } = r ^ { 2 }$

Multiple Choice

Write the given equation in the form $( x - h ) ^ { 2 } + ( y - k ) ^ { 2 } = r ^ { 2 }$ . Identify the center and radius.
- $$x ^ { 2 } + y ^ { 2 } + 22 x + 21 = 0$$

A) $( x + 22 ) ^ { 2 } + y ^ { 2 } = 21$
Center: $( - 22,0 ) ; r = 21$

B) $( x + 22 ) ^ { 2 } + y ^ { 2 } = 21$
Center: $( 0,22 ) ; r = 21$

C) $( x + 11 ) ^ { 2 } + y ^ { 2 } = 100$
Center: $( - 11,0 ) ; r = 10$

D) $( x + 11 ) ^ { 2 } + y ^ { 2 } = 100$
Center: $( 0,11 ) ; r = 10$
