Introduction

In mathematics, a polynomial is an expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication. When a polynomial is expressed in its fully factored form, it provides valuable insights into the behavior and properties of the function. In this article, we will delve into the fully factored form of a complex polynomial, $f(x)=(x-3)(x+3)[x-(2-i)][x-(2+i)]$ , and explore its real and imaginary roots.

Understanding the Fully Factored Form

The fully factored form of a polynomial is a product of linear factors, each of which represents a root of the polynomial. In the given polynomial, $f(x)=(x-3)(x+3)[x-(2-i)][x-(2+i)]$ , we can see that it is a product of four linear factors. The first two factors, $(x-3)$ and $(x+3)$ , represent the real roots of the polynomial, while the last two factors, $[x-(2-i)]$ and $[x-(2+i)]$ , represent the complex roots.

Complex Roots and Conjugate Pairs

In complex analysis, complex roots of a polynomial always occur in conjugate pairs. This means that if a polynomial has a complex root $a+bi$ , then it must also have a complex root $a-bi$ . In the given polynomial, we can see that the complex roots are $2-i$ and $2+i$ , which are conjugate pairs.

Real Roots and Imaginary Roots

To determine the number of real and imaginary roots of the polynomial, we need to analyze the factors. The first two factors, $(x-3)$ and $(x+3)$ , represent two real roots, $x=3$ and $x=-3$ . The last two factors, $[x-(2-i)]$ and $[x-(2+i)]$ , represent two complex roots, $x=2-i$ and $x=2+i$ . Therefore, the polynomial has $\boxed{2}$ real roots and $\boxed{2}$ imaginary roots.

Properties of Complex Roots

Complex roots of a polynomial have several important properties. One of the most significant properties is that complex roots always occur in conjugate pairs. This means that if a polynomial has a complex root $a+bi$ , then it must also have a complex root $a-bi$ . In the given polynomial, we can see that the complex roots are $2-i$ and $2+i$ , which are conjugate pairs.

Implications of Complex Roots

The presence of complex roots in a polynomial has significant implications for its behavior and properties. Complex roots can affect the stability and oscillatory behavior of the polynomial, and they can also impact the polynomial's ability to model real-world phenomena. In the given polynomial, the complex roots $2-i$ and $2+i$ indicate that the polynomial may exhibit oscillatory behavior or have complex eigenvalues.

Conclusion

In conclusion, the fully factored form of a complex polynomial provides valuable insights into its real and imaginary roots. By analyzing the factors, we can determine the number of real and imaginary roots and understand the properties of the complex roots. In this article, we have explored the fully factored form of the polynomial $f(x)=(x-3)(x+3)[x-(2-i)][x-(2+i)]$ and determined that it has $\boxed{2}$ real roots and $\boxed{2}$ imaginary roots.
