Answer:
Step-by-step 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
