Which of the following is -14(5x-2)(x+19)/-7(x+19)(5x-2) simplified? -2 2 -14(5x-2)/-7)(5x-2) -14(x+19)/-7)(5x-2)

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
