Best ResponseYou've already chosen the best response.1Hints: 1. The degree of a polynomial corresponds to the term with the highest degree, including all variables. So in 6xy2 – xy, 6xy^2, the degree is 3, and xy has a degree of 2. Expand (x+1)(x+11) (using FOIL if necessary to find the answer. 3. 3x3 – 21x2 – 27x note the common factor of 3x, which makes 3x3 – 21x2 – 27x=3x(x^27x9). Don't think there are more rational factors.
