The correct option is:
Analysis of the Question:
From the provided images, the differential equation to solve is:
This equation is a second-order Cauchy-Euler differential equation (also known as a homogeneous linear differential equation).
Step 1: Substitution to constant coefficient form
To solve this, we introduce a new independent variable using the substitution:
Using the chain rule, we can relate the derivatives with respect to to derivatives with respect to . Let :
And for the second derivative:
Substituting these expressions into our original differential equation gives:
Expanding and simplifying the operator:
Step 2: Finding the Complementary Function (CF)
To find the complementary function , we solve the homogeneous equation:
The corresponding auxiliary algebraic equation is:
Factoring the quadratic expression:
Which yields the real and distinct roots:
Thus, the solution of the homogeneous equation in terms of is:
Substituting back into the equation:
Step 3: Finding the Particular Integral (PI)
The particular integral is calculated for the non-homogeneous term:
We can write the constant as . According to the rules for finding the PI of an exponential term , we substitute :
Step 4: Writing the General Solution
The complete general solution is the sum of the complementary function and the particular integral:
