Question 110

Multiple Choice

Solve f(x) = g(x) . Find the points of intersection of the graphs of the two functions.
- f(x) =x2−12x+27g(x) =2x2−12x+18\begin{array} { l } f ( x ) = x ^ { 2 } - 12 x + 27 \\g ( x ) = 2 x ^ { 2 } - 12 x + 18\end{array}


A) x=3,x=−3x = 3 , x = - 3
B) x=13,x=−3x = \frac { 1 } { 3 } , x = - 3
C) x=−102,x=102x = - \frac { \sqrt { 10 } } { 2 } , x = \frac { \sqrt { 10 } } { 2 }
D) x=−182,x=182x = - \frac { \sqrt { 18 } } { 2 } , x = \frac { \sqrt { 18 } } { 2 }
