Understand Rational Root Theorem: The Rational Root Theorem states that any rational root, in the form of qp (where p is a factor of the constant term and q is a factor of the leading coefficient), must be a factor of the constant term divided by a factor of the leading coefficient.
List Factors of Constant Term: List all factors of the constant term −7: ±1, ±7.
List Factors of Leading Coefficient: List all factors of the leading coefficient 2: ±1, ±2.
Create Possible Fractions: Create all possible fractionsp/q using the factors of −7 for p and the factors of 2 for q: ±1/1, ±7/1, ±1/2, ±7/2.
