How do you do equations and transversals

in order to do a equation you have to get what has has a letter to one side and for a traversal you have to know that each line is the same as each opposing side

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

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
