For polynomial g(x) = 2x^4-7x^3-2x^2-7x-4
a) Using Rational Zeros Theorem, find out possible rational roots of g
b) Completely factor g(x) by using synthetic division, using possible roots you found in part (a). Determine all the real zeros of g(x)
c) Solve for complex zeros of g. Then, write g in completely factored form over C
d) Graph function g(x), showing real zeros you found above.
