Quadratic Inequalities - Definition, Examples and How to Solve

Quadratic inequalities are a type of algebraic inequality that involves quadratic expressions. A quadratic inequality looks like ax2+bx+c>0, ax2 +bx+c<0, ax2+bx+c≥0 or ax2+bx+c≤, where a, b, and c are constants, and a≠0. It is a fundamental concept in mathematics, particularly in algebra and calculus. They involve expressions containing quadratic polynomials and inequality signs. It is often required in solution sets that fulfill specific criteria. Lets know more about Quadratic Inequalities in detail below. ...
