Introduction

In algebra, trinomials are a fundamental concept that plays a crucial role in solving various mathematical problems. A trinomial is an algebraic expression consisting of three terms, which can be added, subtracted, multiplied, or divided. In this article, we will delve into the world of trinomials and explore the concept of finding the difference between two trinomials. We will examine a specific problem where one of the trinomials is given, and we need to determine the other trinomial.

Understanding Trinomials

A trinomial is an algebraic expression that consists of three terms. The general form of a trinomial is:

ax^2 + bx + c

where a, b, and c are constants, and x is the variable. The first term, ax^2, is the quadratic term, the second term, bx, is the linear term, and the third term, c, is the constant term.

The Problem at Hand

We are given the difference between two trinomials as:

5x^2 + 11x - 16

and one of the trinomials as:

3x^2 - 2x + 7

Our goal is to find the other trinomial.

Approach to Solving the Problem

To find the other trinomial, we can use the concept of addition and subtraction of polynomials. Since we are given the difference between the two trinomials, we can add the given trinomial to the difference to find the other trinomial.

Step 1: Add the Given Trinomial to the Difference

To find the other trinomial, we add the given trinomial to the difference:

(5x^2 + 11x - 16) + (3x^2 - 2x + 7)

Step 2: Simplify the Expression

Now, we simplify the expression by combining like terms:

(5x^2 + 3x^2) + (11x - 2x) + (-16 + 7)

Step 3: Combine Like Terms

Combining like terms, we get:

8x^2 + 9x - 9

Conclusion

Therefore, the expression that could be the other trinomial is:

8x^2 + 9x - 9

This is the correct answer to the problem.

Discussion and Analysis

In this problem, we used the concept of addition and subtraction of polynomials to find the other trinomial. We added the given trinomial to the difference to find the other trinomial. This approach is a fundamental concept in algebra and is used to solve various mathematical problems.

Q: What is a trinomial?

A: A trinomial is an algebraic expression consisting of three terms. The general form of a trinomial is:

ax^2 + bx + c

where a, b, and c are constants, and x is the variable.

Q: What is the difference between a trinomial and a polynomial?

A: A polynomial is an algebraic expression consisting of one or more terms. A trinomial is a specific type of polynomial that consists of three terms.

Q: How do I find the difference between two trinomials?

A: To find the difference between two trinomials, you can subtract one trinomial from the other. For example, if you have two trinomials:

(5x^2 + 11x - 16) and (3x^2 - 2x + 7)
