Question 38

Multiple Choice

Solve the equation using the quadratic formula.
- x2−14x+40=2x2−16x+32x ^ { 2 } - 14 x + 40 = 2 x ^ { 2 } - 16 x + 32


A) x=4x = 4 or x=−2x = - 2
B) x=−322x = \frac { - \sqrt { 32 } } { 2 } or x=322x = \frac { \sqrt { 32 } } { 2 }
C) x=14x = \frac { 1 } { 4 } or x=−2x = - 2
D) x=−172x = \frac { - \sqrt { 17 } } { 2 } or x=172x = \frac { \sqrt { 17 } } { 2 }
