... Step 4: Then, solve for the rest of the roots. Roots can be real or imaginary. If the roots are imaginary, then they occur in conjugate pairs! To set up factors (in parenthesis) just change their signs. ...

Review of complex number arithmetic
... If the graph has one x intercept, this corresponds to the situation where the discriminant is zero. If the graph has NO x intercept, this corresponds to the situation where the discriminant is negative. Thus, imaginary numbers occur “naturally” when using the quadratic formula. 9. Find the solution ...
