Answer
Set each factor equal to zero and solve.
Explanation
## Step 1:The problem states that Jacob has already factored the quadratic inequality into the form \((2x-1)(x+3) < 0\). This means he has already converted the inequality into a product of two factors.## Step 2:The next logical step would be to set each factor equal to zero and solve. This is because the product of two factors is zero if and only if at least one of the factors is zero. By setting each factor equal to zero, we can find the values of
that make the inequality equal to zero. These values are the critical points that divide the number line into intervals where the inequality is either always true or always false.###

## Step 3:Solving the two equations gives the critical points.###
