solutions for the practice test
... Remember that our shortcut for multiplying polynomials is to multiply every combination of a term from the first polynomial and a term from the second polynomial, then add it all up. We get (x3 − 3x + 1)(2x2 − 7) = 2x5 − 7x3 − 6x3 + 21x + 2x2 − 7 = 2x5 − 13x3 + 2x2 + 21x − 7. (b) Indicate which expr ...
