Match each quadratic equation with its roots. tiles a2-a+11+0

To solve this problem you must aply the proccedure shown below:

 You have the following quadratic equation: a^2-a+11=0 and to solve it you must apply the quadratic formula x=-b√(b^2-4ac)/2a

 a=1
 b=-1
 c=11

 The result is

 a1=(1-i√43)/2
 a2=(1+i√43)/2

 The answer is:a1=(1-i√43)/2 and a2=(1+i√43)/2
