Question

What is quadratic and not quadratic?

Answer 1

Explanation:

A quadratic equation must contain

an
`x^(2)` term

and must not contain terms with degrees higher than
`x^(2)`.

A non/not quadratic equation doesn't have an
`x^(2)` term. It also features a term such as
`x^(3)` which isn't allowed in quadratic equations

Answer 2

A quadratic equation contains a quadratic term (x²), as per the name. The quadratic term must be any variable squared. A non-quadratic equation is an equation that does not contain a quadratic term such as x².

The format for a quadratic equation should look like so: ax² + bx + c = 0, in which a, b, and c are all real numbers and a cannot be equivalent to 0. An example of a quadratic could be: 5x² + (-3x) + 5 = 0.

An example of a non-quadratic equation could be: x³ - 81 = 0.

Hope this helps!
