Question:

What values of x will make 16 divided by x (16/x) undefined?

If the value of x is zero then it would be undefined because anything divided by zero has no solution.

Question:

What is the quadratic formula used for?

Inactive
Zoe H.

In algebra, the quadratic formula is used to solved quadratic equations that cannot be solved through simple methods of factoring. This includes all quadratic equations that do not factor easily on the nonzero side of the problem. For example, the equation x^2 + 5x - 6 = 0 can be factored easily whereas the equation x^2 - 6x - 2 = 0 cannot.
