The given two-parameter family is a solution of the indicated differential equation on the interval (−[infinity], [infinity]). Determine whether a member of the family can be found that satisfies the boundary conditions. (If yes, enter the solution. If an answer does not exist, enter DNE.)y = c1ex cos x + c2ex sin x; y '' − 2y ' + 2y = 0

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
