    Answer:

    X=1,  X=3  and  X=-1

    Step-by-step explanation:

    Given the expression (X-1)(X-3)(X+1):

    # To find the rational values of X, we equate the equation to zero:

    (X-1)(X-3)(X+1)=0\\\\X-1=0 \\\therefore X=1 \ \ \ \ ...i\\\\X-3=0\\\therefore X=3 \ \ \ \ \ ....ii\\\\X+1=0\\\therefore X=-1 \ \ \ \ \  ...iii

    Hence for the values of X=3,X=1 and  X=-1 the expression equal 0
