Introduction

Factoring a quadratic trinomial can be a challenging task, especially for students who are new to algebra. However, with the help of a geometric model, factoring a quadratic trinomial can be made easier and more intuitive. In this article, we will use a geometric model to factor the quadratic trinomial $x^2 - 6x + 8$ .

Step 1: Model the Trinomial

To factor the quadratic trinomial $x^2 - 6x + 8$ , we need to model it using a geometric model. We can do this by placing tiles in the Product section to form a rectangle at the top left. The Product section represents the product of two binomials, which will give us the factored form of the quadratic trinomial.

The Geometric Model

The geometric model consists of two parts: the Product section and the Difference section. The Product section represents the product of two binomials, while the Difference section represents the difference between the two binomials.

Step 2: Identify the Factors

To identify the factors of the quadratic trinomial, we need to look at the Product section and the Difference section. The Product section represents the product of two binomials, which will give us the factored form of the quadratic trinomial.

The Product Section

The Product section consists of two parts: the first part represents the product of the first term of the first binomial and the first term of the second binomial, and the second part represents the product of the second term of the first binomial and the second term of the second binomial.

The Difference Section

The Difference section consists of two parts: the first part represents the difference between the first term of the first binomial and the first term of the second binomial, and the second part represents the difference between the second term of the first binomial and the second term of the second binomial.

Factoring the Quadratic Trinomial

To factor the quadratic trinomial $x^2 - 6x + 8$ , we need to look at the Product section and the Difference section. The Product section represents the product of two binomials, which will give us the factored form of the quadratic trinomial.

The Factored Form

The factored form of the quadratic trinomial $x^2 - 6x + 8$ is $(x - 4)(x - 2)$ .
