Introduction

Factoring quadratic expressions is a fundamental concept in algebra that involves expressing a quadratic expression as a product of two binomials. In this article, we will focus on factoring the expression k2+14k+24k^2 + 14k + 24. Factoring quadratic expressions is an essential skill that can be used to solve quadratic equations, simplify complex expressions, and even factorize polynomial expressions.

Understanding Quadratic Expressions

A quadratic expression is a polynomial expression of degree two, which means it has a highest power of two. The general form of a quadratic expression is ax2+bx+cax^2 + bx + c, where aa, bb, and cc are constants, and xx is the variable. In the expression k2+14k+24k^2 + 14k + 24, a=1a = 1, b=14b = 14, and c=24c = 24.

The Importance of Factoring Quadratic Expressions

Factoring quadratic expressions is crucial in algebra because it allows us to simplify complex expressions, solve quadratic equations, and even factorize polynomial expressions. When we factor a quadratic expression, we are essentially breaking it down into its simplest form, which can be used to solve equations and simplify expressions.

Methods of Factoring Quadratic Expressions

There are several methods of factoring quadratic expressions, including:

  • Factoring by Grouping: This method involves grouping the terms of the quadratic expression into two groups and then factoring out the greatest common factor (GCF) from each group.
  • Factoring by Difference of Squares: This method involves factoring a quadratic expression that can be written as the difference of two squares.
  • Factoring by Perfect Square Trinomials: This method involves factoring a quadratic expression that can be written as a perfect square trinomial.

Factoring the Expression k2+14k+24k^2 + 14k + 24

To factor the expression k2+14k+24k^2 + 14k + 24, we can use the method of factoring by grouping. This involves grouping the terms of the quadratic expression into two groups and then factoring out the GCF from each group.

Step 1: Group the Terms

The first step in factoring the expression k2+14k+24k^2 + 14k + 24 is to group the terms into two groups. We can group the terms as follows:

k2+14k+24=(k2+14k)+24k^2 + 14k + 24 = (k^2 + 14k) + 24

Step 2: Factor Out the GCF

The next step is to factor out the GCF from each group. The GCF of the terms in the first group is kk, and the GCF of the term in the second group is 2424. We can factor out the GCF from each group as follows:

k2+14k+24=k(k+14)+24k^2 + 14k + 24 = k(k + 14) + 24

Step 3: Factor Out the Common Factor

The final step is to factor out the common factor from the two groups. The common factor is 11, and we can factor it out as follows:

k2+14k+24=(k+6)(k+4)k^2 + 14k + 24 = (k + 6)(k + 4)

Conclusion

Factoring quadratic expressions is a fundamental concept in algebra that involves expressing a quadratic expression as a product of two binomials. In this article, we focused on factoring the expression k2+14k+24k^2 + 14k + 24 using the method of factoring by grouping.
