The video tutorial explains the rational zeros theorem, which helps find possible real rational zeros of a polynomial function. It involves listing factors of the constant term and leading coefficient, calculating unique possible rational zeros, and identifying non-possible zeros. The tutorial concludes by suggesting graphing the polynomial to visually identify rational zeros.

What does the Rational Zeros Theorem help us find in a polynomial function?

• The possible rational zeros

• The degree of the polynomial

• The derivative of the polynomial

• The integral of the polynomial
