An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign. If the quadratic polynomial = 0, it forms a quadratic equation. Therefore, the standard form of a quadratic equation can be written as: ax² + bx + c = 0 ; where x is an unknown variable, and a, b, c are constants with 'a' ≠ 0 (if a = 0, then it becomes a linear equation).An equation with a degree of 2 is a quadratic polynomial , which means having a maximum of degree 2 .
Given below are some examples of equation with a degree of 2 :
