factorisable造句

Both quintics are solvable by radicals if and only if either they are factorisable in equations of lower degrees with rational coefficients or the polynomial, named " Cayley's resolvent ", has a rational root in, where
Note that in the case of a cubic polynomial, if the cubic is factorisable at all, the rational root test gives a complete factorization, either into a linear factor and an irreducible quadratic factor, or into three linear factors.
It's difficult to find factorisable in a sentence. 用factorisable造句挺难的
