Inequalities of the form
can be solved either algebraically or with technology.
It is crucial to remember that when multiplying both sides of an inequality by a negative number, the inequality changes direction:
Example
Solve the inequality
Subtracting the RHS:
Now we make a table of signs:
So the solution is 0<x<1 or 2<x.
