Graphing a parabola: Plot points to draw your very first parabola
Graphing quadratics: Every quadratic graph boil down to these 3 numbers
Factoring quadratics: An extremely useful trick for solving some equations
The quadratic formula: A method for solving ANY quadratic equation!
Discriminants and roots: A quick way to tell how many solutions a quadratic has
In this lesson, we will learn how to solve quadratics equations with 2 degrees that can be written in the standard form 〖ax〗^2+bx+c=0 where a,b, and c are real numbers and a≠0. A solution of a quadratic equation in standard form is called a root that can have two real solutions, one real solution, or no real solution.
To solve a quadratic equation, we need to write it in standard form, when the quadratic expression equal to zero, then factor it and set each variable factor equal to zero.
To solve a quadratic equation with given solutions we have to perform the process of finding by factoring in reverse.
Quadratic equations: Solving equations in form of 〖ax〗^2 + c = 0 by extracting the roots and sometimes, equations can have two solutions.
To solve a quadratic equation with given solutions we have to perform the process of finding by factoring in reverse.
