Factoring is an important mathematical skill that can be used to simplify equations. It involves breaking down numbers or expressions into their prime factors. This process is useful for solving algebraic equations, as well as for finding the greatest common factor (GCF) of two or more numbers. In this article, we will explore how to solve factoring problems in an easy-to-follow, step-by-step format.

Breakdown the Problem into Steps

The first step in solving a factoring problem is to break it down into smaller, manageable pieces. For example, if the problem requires us to factor a polynomial such as 5x2 + 10x + 6, we would need to identify the factors of 6 (1, 2, 3, and 6) and determine which two numbers multiplied together equal 10x. Once we have identified the factors of 6, we can then use the distributive property to factor the polynomial. The distributive property states that when multiplying a number by a sum or difference, the number must be multiplied by each individual term in the sum or difference. Therefore, 5x2 + 10x + 6 can be rewritten as 5x2 + (3x)(2x) + (2x)(3) + (1)(6).

We can then use the factored form of the polynomial to determine the GCF. In this case, the GCF is 3x, so the polynomial can be further simplified to (3x)(x + 2) + (2)(3). From here, we can factor out the GCF of 3x and rewrite the expression as 3x(x + 2) + (2)(3). Finally, the polynomial can be simplified to 3x(x + 2).

To help illustrate this process, we’ve included a visual below:

Use Shortcuts

Once you’ve mastered the basics of factoring polynomials, you can begin to use shortcuts to quickly factor them. For instance, if you are asked to factor a trinomial such as x2 + 7x + 12, you can use the “difference of squares” shortcut to quickly factor it. The difference of squares states that the product of two consecutive integers (in this case, 7 and 8) can be written as the difference of two perfect squares (in this case, x2 and 12). Therefore, the trinomial can be rewritten as x2 + 7x + 12 = (x + 7)(x + 8).

Another helpful shortcut is the “sum of cubes” shortcut. This shortcut states that the sum of two cubes (in this case, x3 and 8) can be written as the difference of two perfect cubes (in this case, x3 and 27). Therefore, the trinomial can be rewritten as x3 + 8 = (x + 3)(x2 – 9).

To help readers practice using these shortcuts, we’ve included a few practice problems below:

  • Factor 3x2 + 11x + 4 using the difference of squares shortcut.
  • Factor x3 + 20 using the sum of cubes shortcut.

Outline Common Mistakes

When solving factoring problems, there are a few common mistakes that many students make. For instance, one mistake is not recognizing the difference between a binomial and a trinomial. A binomial is an expression with two terms (for example, x + 5), while a trinomial is an expression with three terms (for example, x2 + 7x + 12). If you are asked to factor a binomial, you cannot use the difference of squares or sum of cubes shortcuts, as these shortcuts only apply to trinomials.

Another common mistake is forgetting to factor out the GCF. When factoring a polynomial, it is important to remember to factor out the GCF so that the expression can be simplified to its simplest form. For example, if you are asked to factor the polynomial 10x2 + 15x + 6, you would need to first factor out the GCF of 5x before completing the problem. Without factoring out the GCF, the polynomial cannot be simplified.

To help readers avoid these common mistakes, we recommend following these tips:

  • Carefully read the problem to determine whether it is a binomial or a trinomial.
  • Always factor out the GCF before completing the problem.
  • Double-check your work to ensure that the answer is correct.

Offer Resources
