Solving Inequalities A common application of inequalities is solving them for a variable. For example, consider the inequality. We can solve for the variable here and getthus placing implicit restrictions upon the variable.

A more complex example is. Here is a common mistake: The problem here is that we multiplied by as one of the last steps. We also kept the inequality sign in the same direction.

However, we don't know if the quantity is negative or not; we can't assume that it is positive for all real. Thus, we may have to reverse the direction of the inequality sign if we are multiplying by a negative number. But, we don't know if the quantity is negative either.

A correct solution would be to move everything to the left side of the inequality, and form a common denominator. Then, it will be simple to find the solutions to the inequality by considering the sign negativeness or positiveness of the fraction as varies: We will start with an intuitive solution, and then a rule can be built for solving general fractional inequalities.

To make things easier, we test positive integers.

Therefore, these two aren't solutions. Then we begin to test numbers such as, and so on. All of these work. In fact, it's not difficult to see that the fraction will remain positive as gets larger and larger. But just where doeswhich causes a negative fraction at andbegin to cause a positive fraction?

We can't just assume that is the switching point; this solution is not simply limited to integers. The numerator and denominator are big hints. Specifically, we examine that when the numeratorthen the fraction isand begins to be positive for all higher values of.

Solving the equation reveals that is the turning point. After more of this type of work, we realize that brings about division byso it certainly isn't a solution. However, it also tells us that any value of that is less than brings about a fraction that has a negative numerator and denominator, resulting in a positive fraction and thus satisfying the inequality.

No value between and itself seems to be a solution. Therefore, we conclude that the solutions are the intervals.anthropology; archaeology; architecture; art. art criticism; literary criticism; film theory; biology; composition studies; criminology.
