Question

Possible rational roots of g(x)=2x^3+4x+1

Answer 1

Explanation:

According to the Rational Root Theorem, the possible roots are c/d. Our c is 1, and our d, the leading coefficient, is 2.

The constant is 1. The factors of 1 are:

±1

The leading coefficient is 2 and the factors of 2 are:

±1, ±2

This puts the possible roots, c/d, as:

±1, ±1/2
