Proving algebraic inequalities
... Obviously, the set of solutions of the last inequality is the interval (, 3). To prove an inequality is to determine whether the inequality is always true for all the values of the variables on a certain set of numbers. Example: Prove that x( x 1) 0 , for all positive values of x. Solution: ...
