Introduction

In algebra, factorization is a fundamental concept that helps us simplify and manipulate expressions. It involves breaking down an expression into its constituent parts, which can be added or subtracted separately. In this article, we will focus on fully factorizing the quadratic expression 7t^2 - 14tu. We will explore the steps involved in factorizing this expression and provide a clear explanation of the process.

Understanding the Expression

Before we begin factorizing the expression, let's understand its structure. The given expression is a quadratic expression in the form of at^2 + bt + c, where a = 7, b = -14t, and c = 0. The expression can be written as 7t^2 - 14tu.

Step 1: Identify the Greatest Common Factor (GCF)

The first step in factorizing the expression is to identify the greatest common factor (GCF) of the terms. In this case, the GCF of 7t^2 and -14tu is 7t. We can factor out 7t from both terms to get:

7t^2 - 14tu = 7t(t - 2u)

Step 2: Factor the Remaining Expression

Now that we have factored out 7t, we are left with the expression (t - 2u). This expression cannot be factored further, as it is a linear expression. Therefore, we can write the fully factorized form of the original expression as:

7t^2 - 14tu = 7t(t - 2u)

Conclusion

In this article, we fully factorized the quadratic expression 7t^2 - 14tu. We identified the greatest common factor (GCF) of the terms and factored it out to simplify the expression. We then factored the remaining expression to obtain the fully factorized form. The fully factorized form of the expression is 7t(t - 2u).
