    - (1 x 12) = 22 - 12 = 10 Example 2: 25 26 35 36 (35 x 26) - (25 x 36) = 910 - 900 = 10 Example 3: 63 64 73 74 (73 x 64) - (63 - 74) = 4672 - 4662 = 10 So, from the above examples I can see that the difference is 10, now I will find out the general case algebraically. GENERAL CASE: n n + 1 n + 10 n + 11 (n + 10)(n + 1)

  3. Rational Zeros Portfolio Assignment

    In Part 2, we will be more closely examining the smallest positive roots of several functions. We will also take a look at how these functions relate to each other and try to correlate which changes in a function bring about certain changes in their graphs and in their roots. In Part 3, we will more formally and accurately try to find the established relationship between the rational root of the equation to the leading coefficients of a and the constant term d. We will accomplish this simply by rewriting and rearranging formulas to discover this relationship.
