Polynomial Equations

A Polynomial equations is an equation that can be written in the form
axn + bxn-1 + . . . + rx + s = 0,
where a, b, . . . , r and s are constants.

We call the largest exponent of x appearing in a non-zero term of a polynomial the degree of that polynomial.


A linear equation in two variables is an equation that can be written in the form
Ax + By = C, where A and B are not both 0.

This form is called the standard form of a linear equation.

Graphing linear equations involves three steps:-

Find three ordered pair solutions.
Plot the points found in step 1. The point lines up with both the x value of the ordered pair (x-axis) and the y value of the ordered pair (y-axis).

Draw the graph: A linear equation will graph as a straight line.
