Question 222

Multiple Choice

Solve the equation using the quadratic formula.
- 7x2+10x+2=07 x ^ { 2 } + 10 x + 2 = 0


A) x=5+1114x = \frac { - 5 + \sqrt { 11 } } { 14 } or x=51114x = \frac { - 5 - \sqrt { 11 } } { 14 }
B) x=10+117x = \frac { - 10 + \sqrt { 11 } } { 7 } or x=10117x = \frac { - 10 - \sqrt { 11 } } { 7 }
C) x=5+397x = \frac { - 5 + \sqrt { 39 } } { 7 } or x=5397x = \frac { - 5 - \sqrt { 39 } } { 7 }
D) x=5+117x = \frac { - 5 + \sqrt { 11 } } { 7 } or x=5117x = \frac { - 5 - \sqrt { 11 } } { 7 }
