Question

Are all quadratics factorable?

Answer 1

not all are but most of them are. if you are having a hard time use the quadratic equasion.

Explanation:

Answer 2

t really depends on whether you want to have complex factors or not. If you can have complex factors, every expression can be. If not, then only if b2≥4ac would they be factorable.

Take x2+1, it can be factored into (x−i)(x+i) but none of the factors are real.
