You can download this free course on second degree math equations and inequations in PDF format.
In mathematics, a second degree equation is a polynomial equation of degree 2. In this said equation, x is the unknown and the letters a, b, c represent the coefficients, with a being different from 0. In the set of real numbers, such an equation has at most two solutions. These correspond to the abscissae of the intersection points of y = ax2 + bx + c. The student should be able to correctly draw the graph with the necessary materials. In addition, the student must have a good grasp of the course and be comfortable practicing. In addition, a second degree equation always has two distinct roots or a double root.
This math course on equations and inequations involves the following concepts:
– definition of an equation and an inequation of the second degree with one unknown ;
– put in canonical form;
– calculation of the delta discriminant;
– factorization and sign of the trinomial;
– graphic resolution.
