Determine the Constant That Should Be Added to the Binomial $$x ^ { 2 } + 16 x$$

question 74

Multiple Choice

Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then
write and factor the trinomial.
- $$x ^ { 2 } + 16 x$$

• A) \(64 ; x ^ { 2 } + 16 x + 64 = ( x + 8 ) ^ { 2 }\)
• B) \(8 ; x ^ { 2 } + 16 x + 8 = ( x + 64 ) ^ { 2 }\)
• C) \(256 ; x ^ { 2 } + 16 x + 256 = ( x + 16 ) ^ { 2 }\)
• D) \(16 ; x ^ { 2 } + 16 x + 16 = ( x + 256 ) ^ { 2 }\)
