Answer:

a = 0 makes the equation a linear equation, not quadratic

Step-by-step explanation:

A polynomial expression is quadratic if and only if its highest degree is 2. If the coefficient of the squared term is zero, then the polynomial does not contain a term of degree 2, so is not a quadratic. The coefficient of the squared term must be non-zero.
