NEED HELP ASAPP If f (x)= (x − a)(x − b) where both a and b represent real numbers, which statement is true?

A. The zero of the function is f (0).
B. The zeros of the function are x = a and x = b.
C. The zeros of the function are f(−a) and f(−b).
D. The zeros of the function are x = −a and x = −b.

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?
