Factoring quadratics might seem a bit confusing at first, but it can actually be quite simple once you learn a few easy methods. Here are some techniques that really helped me:
This method is super helpful because it gives you a visual way to see the problem.
First, draw a box and split it into four smaller boxes.
In the top left box, write the number in front of .
In the bottom right box, put the constant term (the number without ).
Now, fill in the other two boxes with two numbers that multiply to give you the constant term and add up to the number in front of .
When you fill in the boxes correctly, the factors will line up nicely. It’s like a little puzzle!
Sometimes, quadratics can be tricky to factor. In those cases, you can use the quadratic formula:
This formula is especially useful when the numbers are a bit complicated. Here, , , and are the numbers in your quadratic equation, which looks like . Just put those values into the formula and you’ll find the solutions, which can help you factor the equation.
This method is a little more involved, but it’s very useful. You can change a quadratic from the form into a perfect square.
Here's how to do it:
Start with .
Factor out , which gives you .
Take half of the coefficient, square it, and then add and subtract that number inside the parentheses.
Once you have your perfect square, you can easily factor it!
This method works great when you have four terms in your polynomial.
First, group the terms into two pairs.
Next, factor out what is common in each pair.
If you do this right, you might notice that you can factor it even more.
Look out for special cases like the difference of squares, perfect squares, or the sum/difference of cubes.
For example, if you see something like , you can quickly recognize it as:
Once you get comfortable with these techniques, factoring quadratics can actually be enjoyable! It’s all about finding the method that works best for you. The more you practice, the better you’ll get—so grab some practice problems and see which technique feels the easiest! You can do it!
