Multiple Choice

Solve Quadratic Equations by Completing the Square
Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then
write and factor the trinomial.
- $$x ^ { 2 } + 18 x$$

• A) \(81 ; x ^ { 2 } + 18 x + 81 = ( x + 9 ) ^ { 2 }\)
• B) \(9 ; x ^ { 2 } + 18 x + 9 = ( x + 81 ) ^ { 2 }\)
• C) \(324 ; x ^ { 2 } + 18 x + 324 = ( x + 18 ) ^ { 2 }\)
• D) \(18 ; x ^ { 2 } + 18 x + 18 = ( x + 324 ) ^ { 2 }\)
