Q

What is the leading coefficient?

A

The first coefficient

It is the coefficient of the term with the highest degree.

17
Q

What is a constant in a polynomial?

A

A term that has no variable

Constants are independent of any variable and remain the same.

18
Q

Define a monomial.

A

A polynomial with 1 term

Examples include 5x or 3y^2.

19
Q

Define a binomial.

A

A polynomial with 2 terms

Examples include x + 3 or 2y - 5.

20
Q

Define a trinomial.

A

A polynomial with 3 terms

Examples include x^2 + 2x + 1.

21
Q

What is a polynomial?

A

A polynomial with 4 or more terms

Examples include x^3 + x^2 + x + 1.

22
Q

What do algebra tiles help understand?

A

Polynomial addition and subtraction

Algebra tiles visually represent polynomials and their operations.

23
Q

What does the legend on algebra tiles identify?

A

If a block is negative or positive

This helps in visualizing the addition or subtraction of polynomials.
