x = 0 or x = 3

Since x is multiplied by (x - 3), in order for x(x-3) to be equal to 0, either x= 0, or x-3=0 (in which case x = 3)

x= 0 or x = 3

In order for this to be a zero, one of the variables has to be a zero. (i.e. Somthing Times Zero = Zero)

Your variables are X, and X-3, so either

X=0 or X-3=0

X=0 or X=3 (add 3 to both sider, or simply move the -3 to the right)

x can equal 0 or 3

it cannot equal -3
