Question

I'll give a medal, it's just one question.
Given the binomials (x-1), (x-3), and (x+5), which one is a factor of f(x)=x^3+6x^2+12x+35?
(x-1)
(x-3)
(x+3)
(x+5)

Answer 1

You could just enter each root in. 1, 3, -3, -5. Or, you could try polynomial long division - divide each factor into the original trinomial. In this case, I reccomend plugging in roots.
