For the polynomial g(x) = 2x4 - 5x3 - 39x2 + 90x + 54, use the Rational Zeros Theorem to list all possible rational zeros of the polynomial. Then identify all roots of the polynomial.

Possible rational roots: +/-

List all the zeros (real or complex) of the polynomial:  

Hint: Remember to enter an irrational number, either use the math quill option (the up arrow to the right of the answer key) or the code sqrt(#)
