Introduction

In algebra, a trinomial is a polynomial with three terms. The degree of a polynomial is the highest power of the variable in any of its terms. For the expression $$5x^3 y^3 + x y^2 + 8$$ to be a trinomial with a degree of 5, we need to find the missing exponent on the $$x$$-term. In this article, we will explore the concept of trinomials and polynomials, and provide a step-by-step solution to find the missing exponent.

Understanding Trinomials and Polynomials

A trinomial is a polynomial with 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 degree of a polynomial is the highest power of the variable in any of its terms. For example, in the polynomial $$x^2 + 3x + 2$$, the degree is 2, because the highest power of $$x$$ is 2.

The Expression Given

The expression given is $$5x^3 y^3 + x y^2 + 8$$. To be a trinomial with a degree of 5, the missing exponent on the $$x$$-term must be found.

Step 1: Identify the Degree of the Given Expression

The degree of the given expression is 3, because the highest power of $$x$$ is 3. To be a trinomial with a degree of 5, the missing exponent on the $$x$$-term must be 2, so that the degree of the expression becomes 5.

Step 2: Find the Missing Exponent

To find the missing exponent, we need to add the missing term to the expression. The missing term must have a degree of 2, so that the degree of the expression becomes 5. The missing term is $$x^2$$.

Conclusion

In conclusion, for the expression $$5x^3 y^3 + x y^2 + 8$$ to be a trinomial with a degree of 5, the missing exponent on the $$x$$-term must be 2. This is because the degree of the given expression is 3, and to be a trinomial with a degree of 5, the missing exponent on the $$x$$-term must be 2, so that the degree of the expression becomes 5.

Example

Let's consider an example to illustrate the concept. Suppose we have the expression $$x^2 + 3x + 2$$. To be a trinomial with a degree of 5, we need to find the missing exponent on the $$x$$-term. The degree of the given expression is 2, because the highest power of $$x$$ is 2. To be a trinomial with a degree of 5, the missing exponent on the $$x$$-term must be 3, so that the degree of the expression becomes 5.

Tips and Tricks

To find the missing exponent, we need to add the missing term to the expression.
The missing term must have a degree that is one less than the desired degree of the expression.
The degree of a polynomial is the highest power of the variable in any of its terms.
