usethe rational zero theorem to find all real zeros of
the polynomisl function.Use the zeros to factor f over the real numbers.
f(x)=x^4+2x^337x^28x+12
what are the real zeros?>
use the real zeros to factor f
f(x)=

Try values of x = ±1, ±2, ±3, ±4, ±6
hint: x = 1 and x = 2 worked for me
so (x1) and (x2) are factors
do either long algebraic division or synthetic division to find the other two factors.
