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^33-7x^2-8x+12

what are the real zeros?>

use the real zeros to factor f
f(x)=

• math -

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.
