## Algebra 2 (1st Edition)

In the given polynomial of degree $4$, there are $4$ zeros. By Descartes' Rule, we can notice form the graph that the function has two x-intercepts and the graph crosses the x-axis in both cases. This means that we have $1$ Negative real zero on the right hand and $1$ Positive real zero on the left hand. Hence, Positive real zeros = 1 Negative real zeros= 1 Imaginary zeros = 2
