![]() ![]() Quadratics are also called second degree polynomials because the highest exponent is 2. Vocabulary: The standard format of a quadratic equation is y = ax 2 + bx + c a, b, c are constants x is the independent variable, and y is the dependent variable. In this section, you will add, subtract, multiply, and graph quadratics. So the value of 'b' can be 0.Chapter 4 - QUADRATICS INTRODUCTION TO QUADRATICS Objectives In the standard form of quadratic equation ax 2 + bx + c = 0, only 'a' shouldn't be a zero. Can 'b' be a Zero in the Standard Form of a Quadratic Equation? The standard form of a quadratic equation is as same as its general form and is expressed as ax 2 + bx + c = 0 where 'a' is non-zero. ![]() What is the Difference Between the General Form of Quadratic Equation and the Standard Form of Quadratic Equation? Thus, the value of 'a' should NOT be a zero in a quadratic equation. If a = 0, then the equation becomes bx + c = 0 which is not quadratic anymore. The standard form of quadratic equation is ax 2 + bx + c = 0.
