Question

Use the factor theorem to determine wether x+1 is a factor of: P(x)=x^5+x^4+x^3+x^2+x+1

Answer 1

P(-1) will be = zero if x+ 1 is a factor

Answer 2

sorry im very slow w. all this can u explain please?

Answer 3

ok P(-1) means the value of P(x) when x = -1

so plug in -1 instead of x in the expression

calculate (-1)^5 + (-1)^4 etc and see if you get 0

Answer 4

ok lemme see

Answer 5

i got zero!
