Just do long division like you would for anything else. Look at the remainder in the quotient after you divide the divisor into the dividend.

P(-1) -2 +1 +11 +30
P(-1) =40
P(-1) Is not 0
so x+1 is not a factor the question.
P(3) 54 -99 -99 +36 + 9
P(3) =-99
x-3 is NOT a factor of the 2nd question.
