Introduction

In algebra, the degree of a polynomial is a crucial concept that helps us understand the properties and behavior of the polynomial. It is defined as the highest power of the variable in the polynomial. In this article, we will explore the concept of the degree of a polynomial and apply it to the given expression $$6x^5 - 4x^2 + 2x^3 - 3 + x$$.

What is the Degree of a Polynomial?

The degree of a polynomial is the highest power of the variable in the polynomial. For example, in the polynomial $$3x^2 + 2x - 1$$, the highest power of the variable x is 2, so the degree of the polynomial is 2.

Identifying the Degree of the Given Polynomial

To find the degree of the given polynomial $$6x^5 - 4x^2 + 2x^3 - 3 + x$$, we need to identify the highest power of the variable x. We can do this by looking at each term in the polynomial and identifying the power of x in each term.

Term 1: $$6x^5$$

The power of x in the first term is 5.

Term 2: $$-4x^2$$

The power of x in the second term is 2.

Term 3: $$2x^3$$

The power of x in the third term is 3.

Term 4: $$-3$$

The power of x in the fourth term is 0, since there is no x in this term.

Term 5: $$x$$

The power of x in the fifth term is 1.

Comparing the Powers of x

Now that we have identified the power of x in each term, we can compare them to find the highest power of x. The highest power of x is 5, which is the power of x in the first term.

Conclusion

Therefore, the degree of the polynomial $$6x^5 - 4x^2 + 2x^3 - 3 + x$$ is 5.

Answer

The correct answer is B. 5.
