Purpose

Quadratic Rush was designed to assist algebra and pre-algebra students in gaining skills which will be useful when they begin factoring quadratic equations. The game can be played by any students with an understanding of addition and multiplication.

Game Play

The game consists of a sequence of questions like: "Find two numbers that add to 7 and multiply to 12." Each problem has exactly one solution. In this case, the two numbers are 3 and 4. The player clicks the number three, and then the number 4. The site then verifies the solution. When you click a number, it appears in the equations at the top of the page. If you realize you have provided an incorrect number, click on the number in the equation, and you will be able to re-enter that number.

Note that the numbers are color-coded with the "keypads"; the first number is blue, and its keypad is blue.  When you are entering the second number (green), the green keypad will appear. This may be helpful if you lose track of which number you are entering.

In some cases, the answers may be negative. In which case, the player clicks the minus sign first to make the number negative.
