Sagot :
Yes, because equations such as
[tex] x^{2} -2x-2=0[/tex]
have irrational roots. Therefore, it would be very difficult (but not impossible) to solve it by factoring method.

yes, because not all quadratic equation are factorable, some quadratic equation can be solve using the quadratic formula or completing the square
