Dr. Eaton moves into the use of Multiplication and Division Techniques in solving inequalities. After covering the fundamental principle and the special case of negative numbers which reverse the inequality sign, you will cement your knowledge with four comprehensive video examples.
If both sides of an inequality are multiplied or divided by the same positive number, the resulting inequality has the same solutions as the original one.
If both sides of an inequality are multiplied or divided by the same negative number, the direction of the resulting inequality must be reversed. The new inequality has the same solutions as the original one.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
