Step By Step Solution
Step 1 of 3
The given polynomial is in descending order. Descartes rule of signs tells us that if a polynomial is written in descending order, the number of sign changes in f(x) will give you the number of positive solutions and the number of sign changes in f(-x) gives you the number of negative solutions.
Given polynomial:
