  1. Evaluate p(5)p(5): Evaluate p(5)p(5). p(n)=(n312n2+47n60)(n4)p(n) = (n^3 - 12n^2 + 47n - 60)(n - 4) p(5)=(5312imes52+47imes560)(54)p(5) = (5^3 - 12 imes 5^2 + 47 imes 5 - 60)(5 - 4) p(5)=(125300+23560)(1)p(5) = (125 - 300 + 235 - 60)(1) p(5)=0p(5) = 0
  2. Evaluate q(5)q(5): Step 22: Evaluate q(5)q(5). q(n)=(n+13)(n4)q(n) = (n + 13)(n - 4) q(5)=(5+13)(54)q(5) = (5 + 13)(5 - 4) q(5)=18imes1q(5) = 18 imes 1 q(5)=18q(5) = 18
  3. Add p(5)p(5) and q(5)q(5): Step 33: Add p(5)p(5) and q(5)q(5). p(5)+q(5)=0+18p(5) + q(5) = 0 + 18 p(5)+q(5)=18p(5) + q(5) = 18
