Solving Quadratic Equations
The below QuickQuestion Interface © generates random questions on solving quadratic equations.
Choose the level of difficulty of the quadratics you want to solve, or choose one of the random options to get a mixture of types.
Decide whether to include negatives in the coefficients, and whether to use x or another random letter.
When typing your answers, use a comma to separate the answers (if applicable). For example "x=3,x=4" or just "3,4". The order of the solutions does not matter.
For answers to formula based questions, you need to type your answers to 2 decimal places. In the case of their being no solutions, type "no solutions" or "none".
Use the buttons to create random questions and show the answers.
There is a 10QQI version of this activity.

Ideas for Teachers
The QQI activities are a great way to get all students working. Put random questions on the board, and then get students to answer them on miniwhiteboards. Once all students have answered, and held up their solutions (with working), reveal the answer to see if they were right. Discuss any misconceptions from the working they have shown, or if they have all got it correct, move on to another question (changing the options to make if more difficult if necessary).
