Question

What quadratic equations can be solved by the quadratic formula but not by factoring?

Working on a test, I know the quadratic formula and all that. Just forgot what makes it un-factorable. Thanks for any help! :)

Answer 1

i guess you are supposed to say quadratics that are "prime" i.e. that are not factorable using integers

Answer 2

the question however is in error, you can factor any quadratic equation, once you know the zeros, or via completing the square
