If you have not studied this subject yet you might have mis-copied the Q.
<span>xy = 20 </span>
<span>x + y = -6 </span>
<span>x + 20/x + 6 = 0 </span>
<span>x^2 + 6x + 20 = 0 </span>
<span>quadratic formula </span>
<span>Select one solution x = - 3 + sqrt(11)i </span>
<span>y = - 6 - [- 3 + sqrt(11)i] = - 3 - sqrt(11)i</span>
