Calculator that can Solve Quadratics

In an exam are we allowed to use one of these or do we have to solve it and write all the working or can we just go from the quadratic to the answer? Assuming that we have to solve it using the quadratic formula.

If you're specifically asked to solve it using the quadratic formula, you need to show your working because the marks are probably going to come from showing you know how to use the formula. You are allowed to use quadratic solvers in exams but you should still show your working. In the case that you've made a mistake somewhere, you'll still get method marks if your working is there.
