Adding and Subtracting Polynomials Mastery

What is a monomial?

• A sum of polynomials

• A polynomial with two terms

• A polynomial with three terms

• A number, variable, or product of a number and one or more variables with whole number exponents

When adding polynomials vertically, what should you do if the degrees of the terms do not match?

• Multiply the terms with different degrees

• Add placeholders for the missing degrees

• Ignore the terms with different degrees

• Subtract the terms with different degrees

What is the first step in subtracting polynomials?

• Combine like terms

• Rewrite the polynomials in descending order

• Distribute the subtraction sign to each term in the second polynomial

• Add placeholders for missing degrees

• 16x^2 - 11x + 3

• 2x^2 + 11x + 3

• 2x^2 - 11x + 3
