Question 1074589
your formula is x * (x-1) = 0


this equation will be true if x = 0 or if x = 1.


if x = 0, you will get 0 * -1 = 0


if x = 1, you will get 1 * 0 = 0


anything times 0 will always be equal to 0.


if you graph this equation by setting y = x * (x-1), your graph will cross the x-axis at the points 0 and 1.


this means that y will be equal to 0 at those values of x.


here's your  graph.
