Solve Polynomial Inequality (In Factored Form) Use Boundary Points & Interval Notation

The polynomial inequality, (x+6)(x-5)^2 is less than zero, is given in factored form. The zeros (boundary points) of the associated equation are found and plotted on the number line. The boundary points divide the number line into 3 regions. Test points are chosen in each region and the inequality is evaluated at each test point. If the inequality is true then that region is part of the solution set. The answer is written in interval notation.
