Otherwise, we will need other methods such as completing the square or using the quadratic formula. The following diagram illustrates the main approach to solving a quadratic equation by factoring method. Notice that the left side contains factors of some polynomial, and the right side is just zero! What we need to do is simply set each factor equal to zero, and solve each equation for x.

The left side of the equation is a binomial. That means I can pull out a monomial factor. The final answer should be the same. Try it out! If not, it is very simple.

Since the product of two numbers is negative, I know that these numbers must have opposite signs. More so, having a sum of positive number implies that the number with the larger absolute value must be positive.

Works out great! Between the coefficients 3 and - 27I can pull out 3. I can easily create a zero on the right side by subtracting both sides by After doing so, the left side should have a factorable trinomial that is very similar to problem 3.

By trial and error, the numbers should be - 2 and 7. You may verify this correct combination.

Cookie Policy.The topic of solving quadratic equations has been broken into two sections for the benefit of those viewing this on the web.

As a single section the load time for the page would have been quite long. This is the second section on solving quadratic equations. In the previous section we looked at using factoring and the square root property to solve quadratic equations. The problem is that both of these solution methods will not always work.

Not every quadratic is factorable and not every quadratic is in the form required for the square root property. It is now time to start looking into methods that will work for all quadratic equations. So, in this section we will look at completing the square and the quadratic formula for solving the quadratic equation.

It is called this because it uses a process called completing the square in the solution process. So, we should first define just what completing the square is. That is required in order to do this. Doing this gives the following factorable quadratic equation. This process is called completing the square and if we do all the arithmetic correctly we can guarantee that the quadratic will factor as a perfect square. Notice that we kept the minus sign here even though it will always drop out after we square things.

The reason for this will be apparent in a second. Now, this is a quadratic that hopefully you can factor fairly quickly. This is the reason for leaving the minus sign. Also, leave it as a fraction. Now complete the square. This one is not so easy to factor. We will do the first problem in detail explicitly giving each step. In the remaining problems we will just do the work without as much explanation. Step 1 : Divide the equation by the coefficient of the x 2 term.

Recall that completing the square required a coefficient of one on this term and this will guarantee that we will get that. Step 3 : Complete the square on the left side.

However, this time we will need to add the number to both sides of the equal sign instead of just the left side. This is because we have to remember the rule that what we do to one side of an equation we need to do to the other side of the equation. Step 4 : Now, at this point notice that we can use the square root property on this equation.

That was the purpose of the first three steps. Doing this will give us the solution to the equation. We will not explicitly put in the steps this time nor will we put in a lot of explanation for this equation. This that being said, notice that we will have to do the first step this time. Here are the two solutions. A quick comment about the last equation that we solved in the previous example is in order.Test and Worksheet Generators for Math Teachers.

Then solve the values of x by taking the square roots of both sides of the equation. I will leave it to you to verify.

This problem is very similar to the previous example. My approach is to collect all the squared terms of x to the left side, and combine all the constants to the right side. The two parentheses should not bother you at all. The fact remains that all variables come in the squared form, which is what we want.

This problem is perfectly solvable using the square root method. So my first step is to eliminate both of the parentheses by applying the distributive property of multiplication.

This allows me to get rid of the exponent of the parenthesis on the first application of square root operation. Well, this is great since I already know how to handle it just like the previous examples. Yep, we have four values of x that can satisfy the original quadratic equation.

In each section, each partner has one equation to solve by a specified method. Then Partner B places the numbers into the empty squares of his own equation given with two missing coefficients and solves the equation. There is an important instruction - the number which has its absolute value less to be put in place of the first missing coefficient.

In Section Two partners repeat the same actions, however this time Partner B starts first. In Section Three, Partner A starts solving first again and it goes still the same way. NOTE: The pages are designed in a way that each partner can solve ten equations or even only six.
