Here are the essential concepts you must grasp in order to answer the question correctly.
Complex Zeros
Complex zeros are solutions to polynomial equations that may include imaginary numbers. They occur when the polynomial does not intersect the x-axis at certain points, leading to roots of the form a + bi, where a and b are real numbers. Understanding how to find complex zeros is essential for analyzing polynomial functions, especially when they have even degrees or repeated roots.

Polynomial Functions
A polynomial function is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients. The degree of the polynomial, determined by the highest power of the variable, influences the number and type of zeros it can have. For example, a fourth-degree polynomial can have up to four zeros, which may be real or complex.

Factoring and the Fundamental Theorem of Algebra
The Fundamental Theorem of Algebra states that every non-constant polynomial function has at least one complex root, and the total number of roots (counting multiplicities) equals the degree of the polynomial. Factoring polynomials can help identify these roots, as it breaks down the polynomial into simpler components, making it easier to find both real and complex zeros.
