Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at a method of using the turning point information given by the polynomial solver to help you to write a quadratic in completed square form. There is a warning though that this method may not get you all or any of the marks in an exam, so you must be careful to look at the wording of the question. It is, however, a great method for verifying your algebraic method.

Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at how to use the inequality feature to solve quadratic inequalities. The first question has two variations of finding a set of values for x which satisfy and inequality. The second involves finding the discriminant algebraically and then using the inequality solver to find viable values for k.
