Answer:

Only X-1

Explanation:


f(x) = x + 5x + 2x - 8 \\ f(x) = 8x - 8 \\ let \: x = 1 \: be \: the \: root \: of \: f(x) \\ f(1) = (8 * 1) - 8 = 0 \\ hence \: 1 \: is \: the \: root \: of \: the \: equation \\ therefore \: x = 1 \\ x - 1 = 0 \\ hence \: x - 1 \: is \: the \: fator \: of \: f(x)
