first take out x: f(x) = x(x^2  5x + 6) = 0 (x(x  3)(x  2) = 0 can you continue?

The zeroes is just where y = 0. So pretend f(x) is your y and plug in 0. 0 = x^3 – 5x^2 + 6x Do you know how to solve this? Just ignore f(x)

I would start by factoring first, all of these numbers have a common factor, x. x (x^2  5x + 6) Now, factor it further by factoring x^25x+6 You get (x3)(x2) you're left with x(x3)(x2) Equal each of these expressions to zero. x=0 x  3 = 0, which is x=3 x  2 = 0, which is x =2
