Hi
In a linear inequality the variable is only present raised to the first power (which is usually not explicitly shown). In a quadratic the square of the variable is present (or implied). The square can be implied in an inequality such as x + 1/x < 6 (x not 0) This is equivalent to x2 - 6x + 1 < 0
Without further information, the only inequality is x2 ≥ 0 (assuming x is real). In the complex domain, there is no inequality.
A bivariate linear inequality.
x2≤64
If the equal sign in a linear equation in two variables is replaced with an inequality symbol, the result is a linear inequality in two variables. 3x-2y>7 x<-5
Basically. If the inequality's sign is < or ≤, then you shade the part under the line. If the inequality's sign is > or ≥, then you shade the part over the line.
There need not be any steps.
if x2 ≠ 16, then: {x | x ∈ ℜ, x ∉ (4, -4)}
x2 square root of x is an expression, not an equation or inequality. It, therefore, has no answer.

A linear inequality is all of one side of a plane. A quadratic inequality is either the inside of a parabola or the outside.
