Question 13

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.
- x2+14xx ^ { 2 } + \frac { 1 } { 4 } x


A) 64;x2+14x+64=(x+8) 264 ; x ^ { 2 } + \frac { 1 } { 4 } x + 64 = ( x + 8 ) ^ { 2 }
B) 18;x2+14x+18=(x+14) 2\frac { 1 } { 8 } ; x ^ { 2 } + \frac { 1 } { 4 } x + \frac { 1 } { 8 } = \left( x + \frac { 1 } { 4 } \right) ^ { 2 }
C) 164;x2+14x+164=(x+18) 2\frac { 1 } { 64 } ; x ^ { 2 } + \frac { 1 } { 4 } x + \frac { 1 } { 64 } = \left( x + \frac { 1 } { 8 } \right) ^ { 2 }
D) 116;x2+14x+116=(x+14) 2\frac { 1 } { 16 } ; x ^ { 2 } + \frac { 1 } { 4 } x + \frac { 1 } { 16 } = \left( x + \frac { 1 } { 4 } \right) ^ { 2 }
