Can anybody help me solve this problem? 3x4-11x3-3x2-6x+8=0?

Question

Can somebody help me find all zeros of the polynomial functions or solve the given polynomial equation. Use the rational zero theorem, describe rule of signs, and possibly the graph of the polynomial function shown by a graphing utility as an aid in obtaining the first zero or the first root.

I meant 3x^4-11x^3-3x^2-6x+8=0

Answer 1

Your question isn't very clear. Do you mean 3 times x to the fourth power?
Better written as 3x^4. Much clearer!
Sorry, can't help you more than that.

Answer 2

it should be 2 not zero
