Whenever you add two or more polynomials your answer should be

• Another polynomial always
• A constant always
• Not necessarily a polynomial all of the time
• A rational expression

Whenever you multiply two or more polynomials...

• Your answer will be a rational expression
• Your answer will be degree 2 all the time
• Your answer will be another polynomial always
• Your answer will always be a constant.

(x-3)(x+4) is an example of

• Multiplication of polynomials
• Subtraction of polynomials
• Addition of polynomials
• Division of polynomials

(3x²+2x-4)+(x³-2x²+3) is an example of what type of operation of polynomials

Whenever you subtract two or more polynomial...

• Your coefficients will always be eliminated
• Your answer will always be another polynomial
• Your answer will always be a constant
• Not necessarily a polynomial all of the time
