2nd degree equation #01 ✅In this class I explain the content 2ND DEGREE EQUATION. An equation is a relationship of equality that involves an unknown value, called unknowns. A 2nd degree equation has the largest 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 x^2 side, the coefficient b, on the x side and the coefficient c is alone and is equal to zero. A 2nd degree 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 1st degree equation. During the class I explain how to identify the coefficients, how to classify them as complete or incomplete equations and how to solve an incomplete equation. #mathematics #equation #enem Link to this video: • 2ND DEGREE EQUATION 9TH GRADE Prof. Gis/ ...
