Definition (keystage 2)
If something is quadratic, it contains the variable squared, but not raised to any higher power. For instance a quadratic equation in x contains x2 but not x3. Similarly a quadratic expression, or a quadratic form, contains its variable(s) squared but not raised to any higher power.
If there is more than one variable, quadratic can mean that they are multiplied together in pairs but not in threes.
