Adding and SUbtracting Monomials

Front

What is a monomial?

Back

A monomial is a polynomial with only one term, which can be a constant, a variable, or a product of constants and variables raised to non-negative integer powers.

What does it mean to add monomials?

Back

To add monomials, combine like terms, which are terms that have the same variable raised to the same power.

What is the result of (4x - 2x^3) + (5x^3 - 4x + 5)?

Back

Combine like terms: (-2x^3 + 5x^3) + (4x - 4x) + 5 = 3x^3 + 5.

How do you subtract the polynomials (2x^3 - 3x^2 + 5x - 7) - (x^3 + x^2 - 2x + 4)?

Back

Distribute the negative sign and combine like terms: (2x^3 - x^3) + (-3x^2 - x^2) + (5x + 2x) + (-7 - 4) = x^3 - 4x^2 + 7x - 11.

What is a like term?

Back

Like terms are terms that have the same variable raised to the same power, allowing them to be combined.

What is the difference between a monomial and a polynomial?

Back

A monomial is a single term, while a polynomial is a sum of two or more monomials.

Front

What is the coefficient in a monomial?

Back

The coefficient is the numerical factor in a monomial, representing how many times the variable is multiplied.
