When can a quadratic equation be solved through factoring? When can a quadratic equation be solved through extracting square roots? What could be done with x%5E2-8x%2B27=0? Try to factorize the quadratic trinomial. What is found?

The given x%5E2-9=0 can be solved either way. This one CAN be factored.

Either (x-3)(x+3)=0 factorized or x%5E2=9 and then x=0%2B-+sqrt%289%29.
