It doesn't factorise.
Hi forum!
I was factoring this polynomial and i got stucked, please help me..
x^5 - 6x^4 + 5x^2 - 16x^2 - 12x - 16
what i did is i grouped them:
( x^5 - 6x^4 + 5x^2 ) + ( - 16x^2 - 12x - 16 )
Then i factored each group:
(x^3) ( x - 5 ) ( x - 1 ) + [ -4 ( 4x^2 - 3x - 4 )]
then i don't know what to do next...
i have tried doing trials and errors using synthetic division but i can't solve it.. help me please..
thanks forum
