Question

is there any shortcut to know whether a quadratic equation can be factorized or not?

Answer 1

you can use discriminant. \[b^2-4ac\]

Answer 2

if it is a perfect square, then you can use factorization method.

Answer 3

because then, it will give you integers or rational roots.

Answer 4

is this only way ?

Answer 5

yeah i understood

Answer 6

you can always actually factorize and see :P

Answer 7

no other easier way i think

Answer 8

Any quadratic equation with existing roots can be factored, but for the "easy" factoring, you gotta have the discriminant a perfect square.
