You don't factor quadratics to solve them when you get to advanced math. =
=20
You use the quadratic equation.  x=3D(-B =F1=FB(B=FD-4AC))/2A where Ax=FD+B=
x+C=3D0.
It is easier to use the POLY function on your calculator.  If you want to=
=20
edit the answers, just save the matrix and type "poly matrixname."

If you don't like that method, use the solver.
