Calculus Examples

Find all the values where the expression switches from negative to positive by setting each factor equal to and solving.
Since does not contain the variable to solve for, move it to the right side of the equation by adding to both sides.
Since does not contain the variable to solve for, move it to the right side of the equation by subtracting from both sides.
Solve for each factor to find the values where the absolute value expression goes from negative to positive.
