Answer:
y2 = (6x + 7)/36 + (Dx + E)e^x
Step-by-step explanation:
The method of reduction of order is applicable for second-order differential equations.
For a known solution y1 of a 2nd order differential equation, this method assumes a second solution in the form Uy1 which satisfies the said differential equation. It then assumes a reduced order for U'' (w' = U'').
The differential equation becomes easy to solve, and all that is left are integration and substitutions.

-(7c-18)-2c> 0
First you have to distribute the minus sign in order to combine like terms
EX: -7c+18-2c> 0 then combine like terms which would get you -9c and solve for c
Ex: -9c +18> 0
then minus 18 from both sides to get -18
Next divide -18 by -9 to have c<2 because when you divide by a negative the signs would flip
