You can put this solution on YOUR website! Please help me to solve this eqn x^3+5x^2+8x+4
-------------
It's not an equation.
I can tell, there's no equal sign.
=====================
Some might assume it's = 0.
It might be, or it might be = 137.
There's no reason to make an assumption.
You can put this solution on YOUR website! x^3+5x^2+8x+4=0 (I am assuming this).
roots will be +/-4 or +/-2 or +/-1
Try (x+1) Synthetic division difficult to show here
-1;;;;;; 1;;;;;5;;;;;8;;;;;;;;4
=== 1==4===4===0
(x+1) (x^2+4x+4)
Roots -1, and repeat at -2.
