Evaluate a quadratic function for complex arguments:

Let , or

Evaluate a), b), c), d)

In each case we can copy the argument in parentheses to the open parentheses in f(x) and simplify.

1. 
2. 
   
3. 
   



4. We can use this latter result in this next task, where we indicate its role with square brackets:

Note that all 3 of the terms in the large parentheses eliminate, with the result

Finally we divide to get

Test Problem: Let . Evaluate the quantities indicated in the table below:
