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

question 272

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: \(( 0,11 ) ; r = 10\)
