plz show me the full process of the solution with clear hand writing thx

1. Solve the IVP x - 2x + x = et Int + et, t > 0, ac(1) = 0, 3(1) = 0. Hint: use the Method of Variation of Parameters for the first term on the RHS and the Method of Undetermined Coefficients for the second. dx d'2 x Note the shorthand x = and x = dt dt2
