[@nopzy5975]

A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign. Examples of quadratic inequalities are: x2 - 6x - 16 ≤ 0, 2x2 - 11x + 12 > 0, x2 + 4 > 0, x2 - 3x + 2 ≤ 0 etc. Solving a quadratic inequality in Algebra is similar to solving a quadratic equation.
