The answer depends on the nature of the inequality: whether it is linear, quadratic or has some other functional form.
You can easily tell by substituting 0 for a.
There are linear functions and there are quadratic functions but I am not aware of a linear quadratic function. It probably comes from the people who worked on the circular square.
Linear.
It is a quadratic equation that normally has two solutions
A linear inequality is all of one side of a plane. A quadratic inequality is either the inside of a parabola or the outside.

There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.

A bivariate linear inequality.
The derivative of a quadratic function is always linear (e.g. the rate of change of a quadratic increases or decreases linearly).
A linear function is a line where a quadratic function is a curve. In general, y=mx+b is linear and y=ax^2+bx+c is quadratic.

No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
A quadratic inequality in x is in the standard form of ax^2+bx+c(>or<)d. Ex. 3x^2+5x+1>4
