True
=============
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form for representing a quadratic equation is:
Here, "x" represents an unknown variable. "a", "b", and "c" are constants.
The condition that "a" is not equal to 0 ensures that the equation is indeed of the second-degree and not a linear equation. If "a" were to be 0, then the equation would be a first-degree or linear equation, not a quadratic.
Hence, the statement you're questioning is true.
