Question

Explain how understanding the Fundamental Theorem of Algebra and using the graphing calculator can help in solving a polynomial function that is a fourth degree polynomial.

Answer 1

Use the calculator to find all the real roots, then use factoring or long division to find any remaining imaginary roots, until you've found four. FTA states that a polynomial has as many roots as it's degree... fourth degree means four total roots.

Answer 2

*or the quadratic formula
