Zeros of Polynomial Functions · Exercise 5

Solve quadratic and higher order equations by factoring.

Find the zeros of the function algebraically. Check by graphing a function on a graphing calculator.

ⓐ $f (x) = 2 x^{3} - x^{2} + 8 x - 4$
ⓑ $f (x) = 3 x^{3} - 12 x$
ⓒ $f (x) = 3 x^{3} + 5 x^{2} - 2 x$

Its source prints no answer for this problem, so there's nothing to check against.
