simplify the expression using long division:
find p(-4) and p(5) for the function p(x) =5x^5-5x^4-10x^2+6x-1
----------
^2Using synthetic division:
-4)....5....-5....0....-10....6....-1
........5....-25...100..-410...1646..|..-6585
---
p(-4) = -6585
The quotient is 5x^4-25x^3+100x^2-410x+1646
===================================================
5)....5....-5....0....-10....6....-1
........5.....20....100...490...2456...12279
---
p(5) = 12279
The quotient is 5x^4+20x^3+100x^2+490x + 2456
===================================================
