Mar 18, 2018 · 5. Equations in Quadratic Form. In this section, we'll come across equations that are in fact quadratic, but they may not look like it at first glance. We'll use either of the following methods to solve such equations: Factoring; Quadratic formula: `x=(-b+-sqrt(b^2-4ac))/(2a)` Example 1. Solve: x 4 − 20x 2 + 64 = 0. Answer

Graphing Quadratic Equations Using the Standard form Y=ax^2+bx+c it isn't that complicated to graph a quadratic function. Keep in mind when a is a negative number the parabola will open down, and when a is a positive number it will open upward.
21.0* Students graph quadratic functions and know that their roots are the x-intercepts. 22.0 Students use the quadratic formula or factoring techniques or both to determine whether the graph of a quadratic function will intersect the x-axis in zero, one, or two points. 23.0* Students apply quadratic equations to physical problems, such as the ... An equation that can be written in the form ax 2 + bx + c = 0 is called a quadratic equation. You can solve a quadratic equation using the rules of algebra, applying factoring techniques where necessary, and by using the Principle of Zero Products .
