usethe rational zero theorem to find all real zeros of
the polynomisl function.Use the zeros to factor f over the real numbers.
what are the real zeros?>
use the real zeros to factor f
Try values of x = ±1, ±2, ±3, ±4, ±6
hint: x = 1 and x = 2 worked for me
so (x-1) and (x-2) are factors
do either long algebraic division or synthetic division to find the other two factors.
