Many high school students have a hard time with the Fundamental Theorem of Algebra (FTA). This can lead to some common misunderstandings:
Misunderstanding Roots: Students often think that all polynomials have roots that are real numbers. They forget about complex roots, which are also important.
Confusion About Multiplicity: The idea of multiplicity can be tricky. Students might not count the total number of roots correctly because they don’t fully understand this concept.
Fear of Complexity: When students see complex numbers, they can feel scared. They might think it’s too hard for them to understand.
To help students with these problems, teachers should focus on showing how polynomials and their roots are connected. Using visual tools and hands-on activities can help make complex numbers less scary and easier to understand.
