Identify which concepts are covered on your quadratic functions homework. Find videos on those topics within this chapter. Watch fun videos, pausing and reviewing as needed. Complete sample problems and get instant feedback. Finish your quadratic functions homework with ease! Writing parabolas in standard, intercept and vertex form Factoring quadratic equations and completing the square Solving a quadratic equation by factoring Solving quadratics with complex numbers as the solution Graphing and solving quadratic inequalities Graphing a system of quadratic inequalities Applying quadratic functions to motion and simple optimization problems Using quadratic functions to model a given data set or situation.

A parabola is the U shape that we get when we graph a quadratic equation. We actually see parabolas all over the place in real life. In this lesson, learn where, and the correct vocab to use when talking about them. By rearranging a quadratic equation, you can end up with an infinite number of ways to express the same thing. Learn about the three main forms of a quadratic and the pros and cons of each. So, you know how to multiply binomials with the FOIL method, but can you do it backwards?

Check out this lesson to learn a method that will allow you to factor quadratic trinomials with a leading coefficient of 1. It will be the same general idea, but there are a few extra steps to learn. Completing the square can help you learn where the maximum or minimum of a parabola is.

If not, you will after watching this video! When you solve a quadratic equation with the quadratic formula and get a negative on the inside of the square root, what do you do? The short answer is that you use an imaginary number.

For the longer, more helpful answer, check out this lesson! When you finish watching this video lesson, you will be able to graph and solve your own quadratic inequality. Learn what steps you need to take and what to watch for. What is a system of quadratic inequalities? What are the steps to graphing them? Find the answers to these questions by watching this video lesson. When you finish, you will be able to graph these yourself. Quadratic functions are very useful in the real world.

Watch this video lesson and learn how these functions are used to model real world events such as a falling ball. Watch this video lesson to learn how quadratic functions are used to model situations and data gathered from real world scenarios.

Notice that after graphing the function, you can identify the vertex as 3,-4 and the zeros as 1,0 and 5,0. There are a lot of other cool things about quadratic functions and graphs. Locate the vertex on the completed table of values. Do you notice any patterns? Look specifically at the f x values. Notice how the f x values start to repeat after the vertex? What are the zeros in the following quadratic equation?

Which of the following is the greatest common factor? Page 4 Question 16 What kind of shape do quadratic graphs always follow? Which of the following are the solutions to the equation below? Which of the following is not an example of a quadratic equation in real life? Find the roots of the equation. Page 5 Question 21 Which statement is true about the inequality below? Which of the following is not a quadratic equation? How many solutions will a quadratic equation always have?

Quadratic Equations Explained A quadratic equation is an equation that looks like this: ax 2 +bx+c = 0, where a, b, and c are numbers, called coefficients. Example: x 2 +3x+4 = 0. You can think about a quadratic equation in terms of a graph of a quadratic function, which is called a parabola. The equation means that you have to find the points on the horizontal axis (x) where the graph intersects with the axis.
