Solving Quadratic Equations
The below QuickQuestion Interface © generates 10 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".
Type the answer in the answer boxes, and check your answers.

Ideas for Teachers
This is a good alternative to the QQI activity, if you just want to put 10 questions on the board. Then you can get answers from students to enter in the boxes before checking them, and correcting as necessary.
However, the real power in this activity is when you get the students using it themselves. In a computer lesson, set them all going on the activity, and get them to repeat until they get every question correct.
Or you can set it as a homework, telling them the conditions to use (different conditions for different students to differentiate the homework). Then get them to do one or two sets, all correct, and to take a screen shot and either email it to you, or, even better, stick it in their books. Since the questions are random, every student will get a different set of questions, and the immediate feedback means they can go back and correct their work straight away.
