I like this formulation better:
A quadratic equation has roots and .
If and , find an expression for the equation in the form . Note that A,B, and C are not the same as a,b
----
a+b = 6, a-b = 4 tells you a=5, b=1
Thus, (x-5)(x-1) = is the quadratic (A=1, B=-6, C=5, in agreement with Viete's Theorem)
