What are the roots of Quadra equation below? 2x^2+12x+11=0

Helllppp

x=-2±√14/1 is the answer

Step-by-step explanation:

2x²+12x+11=0

by using quadratic formula

x=(-b±√b²-4ac)/2a

here a=2,b=12,c=11

x={(-12)±√(12)²-4(2)(11)}/2

x=(-12±√144-88)/2

x=-12±√56/2

x=-6±2√14/2

x=-4±√14/2

x=-2±√14/1

i hope this will help you :)

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
