The video tutorial explains the concept of zeros in polynomials, highlighting their relationship with solutions and roots. It discusses how a polynomial of degree n can have up to n zeros, which may be real or complex. Through examples, the tutorial illustrates scenarios with different types of zeros, including a detailed exploration of cubic polynomials. The video also clarifies the terminology used in different contexts, such as equations having solutions and graphs having roots.

What is a zero in the context of polynomials?

• A number that makes the polynomial equal to zero

• A number that makes the polynomial equal to one

• A number that makes the polynomial undefined

• A number that makes the polynomial equal to infinity

What is a common characteristic of all zeros of a polynomial?

• They make the polynomial equal to zero

How many zeros can a polynomial of degree n have?

• No zeros

• At least n zeros

• Exactly n zeros

• At most n zeros

What is the relationship between the degree of a polynomial and the number of its zeros?

• The degree is equal to or less than the number of zeros

• The degree is equal to or greater than the number of zeros

• The degree is always less than the number of zeros

• The degree is always greater than the number of zeros

What is true about the zeros of the polynomial x^2 + 5?
