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
