Hey can you me posted picture of question : )

The graph is crossing x-axis at the points
a) -1 
b) 5
c) 8 

This means x + 1, x - 5 and x - 8 are the factors of the given polynomial. We can express the polynomial as the product of its factors. So the given polynomial can be expressed as (x + 1)(x - 5)(x - 8).

Thus, the correct answer to this question is option D

X = -1, 5 , 8

answer is D. (x+1)(x-5)(x-8)

cause
x + 1 = 0,x = -1
x - 5 = 0; x = 5
x - 8 = 0; x = 8

5\16 x 2\5 = 10/80simplify to 1/80
