EQUAÇÃO DO 2 GRAU 9° ANO \Prof. Gis/ aula 1

Quadratic Equation #01 ✅In this lesson, I explain the concept of QUADRATIC EQUATIONS. An equation is a relationship of equality that involves an unknown value, called unknowns. A quadratic equation has the highest exponent of the unknown being 2, and its reduced form is given by ax^2 + bx + c = 0, in which the coefficient 'a' is on the side of x^2, the coefficient 'b' on the side of x, and the coefficient 'c' is alone and is equal to zero. A quadratic equation can be classified as complete or incomplete. It can be considered incomplete when it does not have the coefficient 'b' or the coefficient 'c'. The coefficient 'a' can never be zero, since if the coefficient 'a' is zero, it is a linear equation. During the lesson, I explain how to identify the coefficients, how to classify an equation as complete or incomplete, and how to solve an incomplete equation. #mathematics #equation #enem Link to this video:    • EQUAÇÃO DO 2 GRAU 9° ANO \Prof. Gis/ aula 1   Link to related lessons: Quadratic Equation – Lesson 2:    • EQUAÇÃO DO 2 GRAU FÓRMULA DE BHÁSKARA | \P...   Quadratic Equation – Lesson 3:    • EQUAÇÃO DO 2 GRAU  \Prof. Gis/ AULA 3   Linear Equation.
