Find the zeroes of each function. State the multiplicity of multiple zeroes.

y=(x+3)^3

y=x(x-1)^3

I know you're supposed to factor them out, but I'm really not sure how to. Thanks.

The equations are already factored out. For the first one, y is zero at x=3 only. For the second equation, y = 0 when x = 0 or 1.

The multiplicity of the zeroes that come from cubed factors is 3.

    Find the zeroes of the function y=3x^3-3x So I factored that to y=3x(x^2-1) but am not sure about the zeroes. I know that 0 and 1 are zeroes, but am not sure how to get a zeroe from x^2. Thanks. Factor it again to get 3x
