Introduction

In mathematics, polynomial functions are a fundamental concept in algebra and calculus. A polynomial function is a function that can be expressed as a sum of terms, where each term is a product of a constant and a variable raised to a non-negative integer power. Factoring a polynomial function is an essential step in solving equations and inequalities, and it also helps in constructing a rough graph of the function. In this article, we will factor the polynomial function $f(x) = -1x^3 + 5x^2 - 8x + 6$ to find its zero(s) and construct a rough graph of the function.

Understanding the Polynomial Function

The given polynomial function is $f(x) = -1x^3 + 5x^2 - 8x + 6$ . This function has four terms, and each term is a product of a constant and a variable raised to a non-negative integer power. The first term is $-1x^3$ , which means that the coefficient of the term is $-1$ and the variable is raised to the power of $3$ . The second term is $5x^2$ , which means that the coefficient of the term is $5$ and the variable is raised to the power of $2$ . The third term is $-8x$ , which means that the coefficient of the term is $-8$ and the variable is raised to the power of $1$ . The fourth term is $6$ , which is a constant term.

Factoring the Polynomial Function

To factor the polynomial function, we need to find the greatest common factor (GCF) of the terms. The GCF of the terms is the largest expression that divides each term without leaving a remainder. In this case, the GCF of the terms is $-1$ . We can factor out the GCF from each term to get:

f(x) = -1(x^3 - 5x^2 + 8x - 6)

Now, we need to factor the expression inside the parentheses. We can start by looking for two numbers whose product is $-6$ and whose sum is $8$ . These numbers are $-2$ and $-3$ . We can factor the expression as:

f(x) = -1(x^3 - 5x^2 + 2x - 3x - 6)

We can factor out the common terms from the first two terms and the last two terms to get:

f(x) = -1(x^2(x - 5) + 2(x - 3))
