What is 0.63 divided by 0.18

The answer is 3.5. I have included a screenshot that shows the work and how to get 3.5. I hope this helps!

And by the way yes, I do know this is a kinda old question, but I would like points and I have the answer.

- Your friendly (a little bit late) responder!

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
