This chapter discusses quadratic equations in one variable. A second-degree equation in one variable is an equation that can be written in the typical form ax2 + bx + c = 0, where b and c are any constants, and a is any constant except 0 (for, if a = 0, then ax2 = 0, and ...

One way to factor a quadratic expression is to use the FOIL method in reverse. The equation needs to be broken down and the binomials determined. To do that, find two numbers that add to the middle term of the trinomial and multiply to the constant on the end. Using the example from ...
Quadratic functions have defining equations in which the highest power of the variable is 2. A linear function is one where the equation defining the function is of the form y = mx + c. The highest power of a variable is 1. This is only one type of function. Here we look at another...
