Lower-degree polynomials will have zero, one or two real solutions, depending on whether they are linear polynomials or quadratic polynomials. These types of polynomials can be easily solved using basic algebra and factoring methods.
How do we solve polynomials? That depends on the Degree! Degree. The first step in solving a polynomial is to find its degree. The Degree of a Polynomial with one variable is ..... the largest exponent of that variable. When we know the degree we can also give the polynomial a name:
This topic covers: - Adding, subtracting, and multiplying polynomial expressions - Factoring polynomial expressions as the product of linear factors - Dividing polynomial expressions - Proving polynomials identities - Solving polynomial equations & finding the zeros of polynomial functions - Graphing polynomial functions - Symmetry of functions
Solve an equation, inequality or a system. 2.1 Introduction. If a is any real number, then a1=a, a2=aa, a3=aaa and, in general, if n is any positive integer, the symbol an is deļ¬ned by the equation. an=aa … a (n factors) In the symbol an,a is called Hie base and n is called the exponent.
Most often when we talk about solving an equation or factoring a polynomial, we mean an exact (or analytic) solution. The other type, approximate (or numeric) solution, is always possible and sometimes is the only possibility. When you can find it, an exact solution is usually better.

Demonstrates the steps involved in solving a general polynomial, including how to use the Rational Roots Test and synthetic division. Points out when using a graphing calculator can be very helpful.
Solve quadratic equations by factoring; Solve equations with polynomial functions; Solve applications modeled by polynomial equations
Because of the strict definition, polynomials are easy to work with. For example we know that: So you can do lots of additions and multiplications, and still have a polynomial as the result. Also, polynomials of one variable are easy to graph, as they have smooth and continuous lines. Example: x4−2x2+x. smooth the curve is?
