Question 1172954
For the standard form polynomial
{{{f(x)=2x^4-13x^3+2x^2+82x-40}}}
 find its roots and write it as the product of linear factors.
Use synthetic division, try x=4
:
.. _______________________
 4|2 - 13 + 2 + 82 - 40
. . .+  8 -20 - 72 + 40
.  -----------------------
.  2 - 5 + 18 + 10
Factors are
(x-4)(2x^3 - 5x^2 - 18x + 10)
I don't think you can get more than 1 linear factor is this
