Quadratic Polynomial vs Quadratic Equation
highA quadratic polynomial is an expression of degree 2, while a quadratic equation is that expression written equal to zero.
If the question asks for roots, first check that the expression is written as an equation equal to zero.
Standard form and coefficients
highThe standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are coefficients and a ≠ 0.
Always compare the given equation term by term with ax^2 + bx + c = 0 before using any formula.
Identifying a Quadratic Equation
highA quadratic equation is any equation that can be simplified to ax^2 + bx + c = 0 with a ≠ 0.
Always simplify first. The equation is quadratic only if the highest power after simplification is exactly 2.
