Question 156

Multiple Choice

Add the proper constant to each binomial so that the resulting trinomial is a perfect square trinomial. Then factor the
trinomial.
- x2+211x+x ^ { 2 } + \frac { 2 } { 11 } x + ____


A) x2+211x+2121=(x+111) 2x ^ { 2 } + \frac { 2 } { 11 } x + \frac { 2 } { 121 } = \left( x + \frac { 1 } { 11 } \right) ^ { 2 }
B) x2+211x+1121=(x+111) 2x ^ { 2 } + \frac { 2 } { 11 } x + \frac { 1 } { \underline { 121 } } = \left( x + \frac { 1 } { 11 } \right) ^ { 2 }
C) x2+211x+111=(x+1121) 2x ^ { 2 } + \frac { 2 } { 11 } x + \frac { 1 } { \underline { 11 } } = \left( x + \frac { 1 } { 121 } \right) ^ { 2 }
D) x2+211x+4121=(x+211) 2x ^ { 2 } + \frac { 2 } { 11 } x + \frac { 4 } { 121 } = \left( x + \frac { 2 } { 11 } \right) ^ { 2 }
