The video tutorial explains how to write a polynomial function given its zeros. It introduces the concept of reverse factoring, where zeros are converted into factors using the zero product property. The tutorial demonstrates the multiplication of binomials using the box method to derive the polynomial function. Finally, it presents the polynomial function and discusses naming it as F of X.

What is the final polynomial function derived in the tutorial?

F(x) = X^3 - 2X^2 + X + 6

F(x) = X^3 + 2X^2 - X - 6

F(x) = X^3 + X^2 - 2X - 6

F(x) = X^3 - 3X^2 + 2X + 6
