please answer questions 1-2 (a&b)

1. Here is a solution to solving the equation 5x e* + 6xe* + ex = 0: 5 x2 et + 6xet tex = 0 ex (5x2 + 6x + 1) = 0 5x2 + 6x +1 =0* * (5x + 1)(x + 1) =0 X = Answer the following: At the step marked **, what did we do? Moreover, why are we allowed to do that? 2. Solve the following equations. Check your answers whenever relevant: (a) log3(x + 1) - 10g3(x - 1) = 2 (b) 5* = 7x+1
