Is x(4x^2-16) completely factored? if not, what other factoring can occur
A. no; the binomial is a difference of two squares and can be factored into two binomials.
B. no; 4 can be factored from each term of the binomial AND the resulting binomial is a difference of two squares that factors into two binomials.
C. no; 4 can be factored from each term of the binomial.
D. yes; the polynomial is completely factored.
