Answer to Problem 94RE
The solution using interval notation is
Explanation of Solution
Given information:
The given inequality is
Formula used:
In order to solve an inequality, the following things can be done.
• Add the same quantity to each side of the inequality
• Subtract the same quantity from each side
• Multiply or divide each side by the same positive quantity and If multiplied ordivided each side by a negative quantity, then the inequality symbol must be reversed.
In case of nonlinearinequality, the function may be factorized and solved further long division method etc.
