Classify a polynomial and determine degree and leading coefficient

The video tutorial discusses the use of fractions in polynomials, emphasizing that a polynomial can include fractions as long as there is no variable in the denominator. It explains the structure of polynomials, highlighting the importance of descending order and identifying the degree and leading coefficient. The tutorial concludes by affirming that a polynomial remains valid with fractions under these conditions.

What is a key factor that determines whether a mathematical expression is a polynomial?

• It must be in ascending order.

• It must have a leading coefficient of 1.

• It must have a variable in the denominator.

• It must not have a variable in the denominator.

Why is it acceptable for a polynomial to have a fraction as a leading coefficient?

• If the fraction is positive.

• Because fractions are always allowed in polynomials.

• Only if the fraction is a whole number.

• As long as the polynomial is in descending order.
