You can put this solution on YOUR website! I need to use Rational Zero Theorum to solve x^4-5x^3-48x^2-80x-24=0
Also what is the solution set for this equation? How do you find the solution set?
---------------
Start by trying the integer factors of 24
±1
±2
±3
±4
etc
-------
f(x) = x^4-5x^3-48x^2-80x-24
-------
If, eg, +1 is a zero, then divide by (x-1) and continue.
----------
You can use Excel to test for zeroes.
A graphing calculator will find them for you, too.
