Concept explainers
Work all of the problems in this self-test without using a calculator. Then check your work by consulting the answers in the back of the book. Where weaknesses show up, use the reference that follows each answer to find the section in the test that provides the necessary review.
Problems 2–6 refer to the following polynomials:
(A) 3x – 4 (B) x + 2
(C) 2 – 3x2 (D) x3 + 8

- Find the results of the operation indicated in the following problems.arrow_forwardwhen completing an additional problem, such as 123+423, you would carefully line up the numbers vertically and add the digits in each place. How does expanding the numbers to (1•10^2)+(2•10^1)+(3•10^0) and (4•10^2)+(2•10^1)+(3•10^0) make this addition problem more like a polynomial addition problem?arrow_forwardExplain why the terms of the polynomial y to the second power plus 7 are said to be relatively prime.arrow_forward
