Find roots of:
I need to set =0 then factorise. I know that this polynomial has coefficients of 1,2,4,8 and there is a rule to factorise this however, i don't know it.
Also, i believe a high order polynomial will be included in my exams. Are there any other "special" polynomials such as this which i should look out for to make factorizing easier as it has been suggested a polynomial such as this will come up...
Thanks
ADDED: i should add, this is not a homework question. I have the roots to be (s+2)(s^2+4)...but forgot to note how to arrive at this
