Using the GED Calculator with the Quadratic Formula

A GED student, Pamella, emailed us a quadratic equation she had been trying to solve using the quadratic formula. She made a mistake with the negatives but then as I was trying to work the problem, I made a simple calculation error. Even math teachers make calculation errors, ya'll! It's so easy to make an error because the quadratic equation has so many steps! Follow along as Kate shows you how to avoid all those silly mistakes using your GED calculator, the TI30-XS Multiview.
