In the last two sections of this chapter we desire to discuss solving equations & inequalities that have absolute values. We will look at equations along with absolute value in them in this section.
However, before solving first we must have a brief discussion of just what absolute value is.
The notation for the absolute value of p is |p|. Note as well that the absolute value bars are not parentheses and in several cases don't act as parentheses so be careful with them.
There are two ways to describe absolute value. There is geometric definition & a mathematical definition. We will look at both.
Solve 2 x 10 - x 5 - 4 = 0 . Solution We can reduce this to quadratic in form using the substitution, u = x 5 u 2 = x 10 By using this substitution the equa
