Factoring Binomials Worksheet Worksheet March 21, 16 views.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.

Solving Quadratic Equations by Factoring - Basic Examples

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. Since we received integer and fractions as solutions, we could have just factored this equation from the start rather than used completing the square.Solving quadratic equations worksheets pdf questions with answers included.

The common way to solve quadratic equations is by factorisinghowever not all quadratic equations can be factorised. In order to factorise quadratics students must have a good grasp of expanding double brackets.

Quadratic equations that cannot be factorised can be solved using the quadratic formula. Sometimes the solutions we find when we solve equations by quadratic formula are not "real".
