Can you me with number 6,8,10 and 12 i never 12 can you explain how you find the answer

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
