Unformatted text preview: es that involve polynomials of degree at least two. Or, to put it in other
words, the polynomials won’t be linear any more. Just as we saw when solving equations the
process that we have for solving linear inequalities just won’t work here.
Since it’s easier to see the process as we work an example let’s do that. As with the linear
inequalities, we are looking for all the values of the variable that will make the inequality true.
This means that our solution will almost certainly involve inequalities as well. The process that
we’re going to go through will give the answers in that form. Example 1 Solve x 2 - 10 < 3 x .
There is a fairly simple process to solving these. If you can remember it you’ll always be able to
solve these kinds of inequalities.
Step 1 : Get a zero on one side of the inequality. It doesn’t matter which side has the zero,
however, we’re going to be factoring in the next step so keep that in mind as you do this step.
Make sure that you’ve got something that’s going to b...
