Question

What is the general form for a quadratic equation? What does the equation have to be equal to, so that it can be referred to as a Quadratic equation ?

Answer 1

A quadratic equation can be used to express a parabola using a mathematical function.

Quadratic equations are polynomials where the degree is 2, that is the power of the leading coefficient is 2.

The general form of a quadratic equation is given to be:

`ax^2+bx+c=0`

where a, b, and c are real numbers and

`a\\eq0`

Note that the equation is only a quadratic equation if the function equals 0. Otherwise, what we have is termed a quadratic expression.
