What should you remember to do when adding and subtracting polynomials?

• Ignore the negative sign

• Multiply all terms

• Distribute the negative sign to every term

• Combine all terms

When multiplying two binomials, what method should you use?

• Distribute the negative sign

• Add the exponents

• Combine like terms

• FOIL

What is the result of multiplying (3x - 5)(3x - 5)?

• 9x^2 - 25

• 9x^2 - 15x + 25

• 9x^2 - 30x + 25

What is the first step when distributing a binomial times a trinomial?

• Distribute the first term of the binomial to all terms of the trinomial

• Add the exponents

• Use FOIL method

• Combine like terms

What is the result of distributing 5w^2 to the terms in (2w^2 + w - 3)?

• 10w^4 + 5w^3 - 15w^2

• 10w^4 - 5w^3 - 15w^2

• 10w^4 - 5w^3 + 15w^2

What should you remember when distributing a negative term?

• Ignore the negative sign

• Combine it with the first term

• Distribute it as a positive term

• Distribute it as a negative term

What is the result of combining like terms in the expression 10w^4 + 5w^3 - 15w^2 - 8w^2 - 4w + 12?

• 10w^4 + 5w^3 - 23w^2 - 4w + 12

• 10w^4 + 5w^3 - 7w^2 - 4w + 12

• Distribute the negative sign

What is the result of FOILing (2x - 3)(2x - 3)?

• 4x^2 - 6x - 9

• 4x^2 - 12x - 9

• 4x^2 - 6x + 9
