Plotting points on the coordinate plane is the foundation for graphing equations. Then hit enter and it will spit out the x values of the zeros. The use of polynomials is seen in pure mathematics also, such as - algebraic geometry, modern algebra, polynomial rings etc. The following figure show how to find the zeros or roots of a polynomial function Graphically or using the Rational Zeros Theorem.
Zeros of Polynomial Functions How to use the graphing calculator to find real zeros of polynomial functions. Then type comma x because x is the variable we are solving for. Within a competitive market, this is an advantage that you wont find anywhere else. You should get something that looks like this.
