Formula and explanation
The general form of a quadratic inequality in one variable is: ax² + bx + c > 0 (or < 0, ≥ 0, ≤ 0 ), where a eq 0. Applicable Condition: a, b, c are real numbers, a eq 0. Explanation: This is the basic form for solving quadratic inequalities. It must be transformed into this standard form before solving.
