WebI seems that the correct Algebra way to solve this would be to subtract e^x from 1/ (x (x-1) (x-2) and set it equal to zero. i.e. 1/ (x* (x-1)*x-2))-e^x=0. This is actually kind of what I did … WebSolving an equation symbolically means that expressions can be used for representing the solutions. For example, the equation x + y = 2x – 1 is solved for the unknown x by the expression x = y + 1, because substituting y + 1 for x in the equation results in (y + 1) + y = 2 (y + 1) – 1, a true statement.
