This is an introductory video on how to identify a quadratic function. This video explains what a quadratic function is and what the graph of a quadratic function looks like. The instructor goes through 4 examples of quadratic functions...

FOIL= first, outside, inside, last. Use this method to multiply two binomials. The teacher demonstrates this method using variables. Then she demonstrates with numbers and variables and writes out each term being multiplied. Finally,...

Yes, it's a word problem but you have all the information you need to solve it. You have a formula, and they have given you a value to plug in. So get to it and write out the formula, plug in the value and solve this word problem.

So you are looking for all the possible binomial factors of a trinomial expression? First find the factors of the coefficients. Then set up a table or template to do a guess and check. Write out, using the template, all the possible...

A polynomial is the sum of one or more monomials. They are identified by the number of terms they have. Monomials, binomials, trinomials, find out what these terms identify.

What is the lowest point of a 'U' shaped parabola called? It's called the minimum of a quadratic function, also known as, the vertex.

What is the highest point of an upside down parabola called? It's called the maximum of a quadratic function, also known as, the vertex.

Now your lesson will be complete. Scholars first review the process of completing the square to rewrite quadratics in vertex form. The method shown here is to first take half of the coefficient of x and finding the perfect square, then...

What happens when factoring fails? Viewers learn how to rewrite quadratics that cannot be factored. They learn to complete the square to write quadratic in vertex form.

Add another method to your arsenal by solving quadratics using completing the square. Scholars learn to solve quadratic equations that cannot be solved by factoring. The preferred method for this video is completing the square.

The instructor discusses how to solve a quadratic equation by completing the square. The verbal explanation is fairly complete, but the writing of the steps is rather vague.

FOIL= first, outside, inside, last. Use this method to multiply two binomials. The teacher demonstrates this method using variables. Then she demonstrates with numbers and variables and writes out each term being multiplied. Finally,...

Watch this video and find out how to graph a quadratic equation when it's in intercept form! After going through the different forms of quadratic equations, an instructor leads viewers through an example problem. For the example problem,...

When first looking at this polynomial and thinking about factoring it into binomials, the task seems daunting because the numbers just look icky. But watch this video and see the instructor demonstrate how to factor by the A-C method....

There are many methods that can be used to solve a quadratic equation. The teacher demonstrates how to use the square root method to solve this equation. But wait, how can there be two solutions? And how can one of them be a negative...

Making a table for a quadratic function is not so complicated. Here are a few tricks to make it easier. One trick is to find the axis of symmetry and another is to find the vertex. These two values can be used to pick values to plug in...

Factor the given quadratic equation by using the guess and check method. Then use the zero product property to find the solutions to the quadratic equation. Don't forget to check both of the answers.

What does the graph of a linear equation look like? How about a graph of a quadratic equation? What does a graph of an exponential function look like? Watch this video and see as the instructor illustrates and explains each of these...

The form of a quadratic function can help you determine if the vertex of a quadratic equation will be a minimum or a maximum of the function. If the coefficient of 'a' in the quadratic form of the equation is positive the vertex will be...

Trying to find the vertex of a quadratic equation? Remember that the vertex is the minimum or maximum point of the quadratic equation and can be identified on a graph of the equation. First use the axis of symmetry formula to find the...

What do you get when you graph a quadratic function? Not a line, that's the graph of a linear equation. The graph of a quadratic function is a curved line, either opening upward like a smile, or opening downward like a frown. The...

What things need to be done to graph a quadratic function? Well, first, find the axis of symmetry, then find the vertex of the parabola, then create a table and plug in some x-values to get the resulting y-values. Now write the values as...

Writing a quadratic equation in standard form gives values for a, b, and c that can be used to find several pieces of information about the graph of the equation. Knowing a, b, and c-values allows one to find the axis of symmetry, the...

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered...
