Understanding the Original Function

The original function is given by the equation $(z-1)\left(z^3+2z^2+3z+6\right) = 0$ or $(z-1)\left(z^2+3\right)(z+2) = 0$ . This equation represents a polynomial function of degree 4, which can be factored into three separate factors: $(z-1)$ , $(z^2+3)$ , and $(z+2)$ . Each of these factors represents a quadratic or linear function that contributes to the overall behavior of the original function.

The Roots of the Original Function

To find the roots of the original function, we need to set each factor equal to zero and solve for $z$ . This will give us the values of $z$ that make the function equal to zero.

Roots from the Linear Factor

The linear factor $(z-1)$ can be set equal to zero to find its root:

z - 1 = 0

Solving for $z$ , we get:

z = 1

This is the root of the linear factor.

Roots from the Quadratic Factors

The quadratic factors $(z^2+3)$ and $(z+2)$ can be set equal to zero to find their roots:

z^2 + 3 = 0

z + 2 = 0

Solving for $z$ in the first equation, we get:

z^2 = -3

z = \pm \sqrt{-3}

Since the square root of a negative number is an imaginary number, the roots of the first quadratic factor are complex numbers:

z = \pm i\sqrt{3}

Solving for $z$ in the second equation, we get:

z = -2

This is the root of the second quadratic factor.

Summary of the Roots

In summary, the roots of the original function are:

$z = 1$ from the linear factor
$z = \pm i\sqrt{3}$ from the first quadratic factor
$z = -2$ from the second quadratic factor

These roots represent the values of $z$ that make the original function equal to zero.

Graphical Representation of the Roots

The roots of the original function can be represented graphically on the complex plane. The complex plane is a two-dimensional plane where the x-axis represents the real part of a complex number and the y-axis represents the imaginary part.

The root $z = 1$ is a real number and can be represented as a point on the x-axis.

The roots $z = \pm i\sqrt{3}$ are complex numbers and can be represented as points on the y-axis.

The root $z = -2$ is a real number and can be represented as a point on the x-axis.

Conclusion

In conclusion, the original function is a polynomial function of degree 4 that can be factored into three separate factors: $(z-1)$ , $(z^2+3)$ , and $(z+2)$ . The roots of the original function are $z = 1$ , $z = \pm i\sqrt{3}$ , and $z = -2$ . These roots represent the values of $z$ that make the original function equal to zero.

Appendix

The original function can be represented in a variety of forms, including:

Factored form: $(z-1)\left(z^3+2z^2+3z+6\right) = 0$
Expanded form: $z^4 + 2z^3 + 3z^2 + 6z - 1 = 0$
Polynomial form: $z^4 + 2z^3 + 3z^2 + 6z - 1 = 0$

Each of these forms represents the original function in a different way, but they all describe the same mathematical object.
