F(x) = (x^2 + 3x − 4) and g (x) = (x+4) find f/g and state the domain.

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

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?
