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.
- $$x ^ { 2 } - 12 x$$

A) $36 ; x ^ { 2 } - 12 x + 36 = ( x - 6 ) ^ { 2 }$
B) $- 36 ; x ^ { 2 } - 12 x - 36 = ( x - 6 ) ^ { 2 }$
C) $- 144 ; x ^ { 2 } - 12 x - 144 = ( x - 12 ) ^ { 2 }$
D) $144 ; x ^ { 2 } - 12 x + 144 = ( x - 12 ) ^ { 2 }$
