Add the Proper Constant to the Binomial So That the Resulting

Multiple Choice

Add the proper constant to the binomial so that the resulting trinomial is a perfect square trinomial. Then factor the
trinomial.
- $$x ^ { 2 } - 13 x$$

A) $x ^ { 2 } - 13 x + \frac { 13 } { 2 } = \left( x - \frac { 13 } { 2 } \right) ^ { 2 }$
B) $x ^ { 2 } - 13 x - \frac { 169 } { 4 } = \left( x - \frac { 13 } { 2 } \right) ^ { 2 }$
C) $x ^ { 2 } - 13 x + 169 = ( x - 13 ) ^ { 2 }$
D) $x ^ { 2 } - 13 x + \frac { 169 } { 4 } = \left( x - \frac { 13 } { 2 } \right) ^ { 2 }$
