Which polynomial is a quadratic factor of 27x^3+64

Weren't there several answer choices?

I notice that 27x^3+64 factors into (3x+4)(9x^2-12x+16).  The 2nd factor is the quadratic factor that you wanted.

In general, a^3+b^3 = (a+b)(a^2-ab+b^2).

Is there more to the question?

Ithink the right answer could be 50%
