Select all of the following for which there exist nonzero constants which can be substituted into the equation to make it true. [Hint: For at least one of these you may want to compare the left and right side as x approaches -5.] > a (x - 10) (x + 5) a (x - 10) (x + 5) = = a (x - 10) (x + 5) 6 None of the Above = b X 10 b X 10 b X 10 + + с x + 5 с x + 5 +
