A quadratic equation, when written in the standard form, has three terms.
Therefore the middle term of a quadratic equation is the term having a single x in it. It is the term in which the variable coefficient is x. The exponent on the variable in the middle term of a quadratic equation is 1.
The middle term is very important as it is split into two terms when factoring a quadratic equation by the method of splitting the middle term.
For example, the middle term of the following quadratic equations are:
- The first term is the term containing x squared in it. Example, 2x^2
- The second term is the term containing a single x in it. Example, 2x
- The third term is a number. Example, 2.

The middle term is very important as it is split into two terms when factoring a quadratic equation by the method of splitting the middle term.
For example, the middle term of the following quadratic equations are:
- 2x^2 + 3x + 8 = 0; middle term is 3x
- 4x^2 - 5x + 6 = 0; middle term is -5x
- x^2 - 9 = 0; there is no middle term
