Question 762058
I am trying to get this {{-3x^3(x-2)^2(x+5)=0}} to polynomial function. 

the example i have is -3x^3(x-2)^2(x+7)=0 and its saying that the way it should be is -3x^6-9x^5+72x^4-84x^3=0

I don't understand how I have to distribute the parenthesis.

Not sure what you mean by "get ... to polynomial function."
It's an equation.  Usually they're to be solved, in this case, for x.
