Please answer the questions correctly. ### Solving a Differential Equation Using the Frobenius Method#### Given Differential Equation\[ 12x^2y'' + 23xy' + (12x^2 - 1)y = 0 \]#### Step 1: Determine the Indicial EquationUsing the variable \( r \), the indicial equation is found as follows:\[ 12r^2 + 11r - 1 = 0 \]#### Step 2: Find the Recurrence RelationTo determine the recurrence relation, use:\[ a_n = \frac{(-1)^{n-1} \cdot 12^{n-1}}{(r+n)(12(r+n-1+23)-1)} \]This should give:\[ a_{n-2} \text{ for } n = 2, 3, \ldots \]#### Step 3: Find the Roots of the Indicial RelationSolving the indicial equation \( 12r^2 + 11r - 1 = 0 \) gives us:- Number of roots: Two- Roots are: \[ r_1 = \frac{1}{12} \] \[ r_2 = -1 \]#### Step 4: Find the Series Solution \( (x > 0) \) Corresponding to the Larger RootThe series solution can be expressed as:\[ y_1(x) = x^{r_1} \left[ 1 + \sum_{n=1}^{\infty} \frac{(-1)^n 6^n x^{2n}}{n! \cdot 37 \cdot 61 \cdot (24n+13)} \right] \]### SummaryThis step-by-step process outlines the application of the Frobenius method to find the series solution to the given differential equation while considering the indicial equation, recurrence relation, and roots of the indicial relation. The final series solution corresponds to the larger root found. ### Differential Equations: Identifying Regular Singular Points and Solving Indicial Equations**Problem Statement:**Show that the given differential equation \(3x^2y'' + \left(2x^2 + \frac{3}{4}\right)y = 0\) has a regular singular point at \(x=0\).\[ xp(x) = \]\[ x^2 q(x) = \]---**Find Indicial Equation:**\[0 = \]---**How many roots does the indicial equation have?**[Choose one ▼]---**Find the Recurrence Equation:**\[a_n = \][Choose one ▼]---**Explanation of Steps and Concepts:**1. **Identifying a Regular Singular Point:** - For a differential equation of the form \(a_2(x)y'' + a_1(x)y' + a_0(x)y = 0\), if \(a_2(0)=0\), this implies a singular point. To check if it is regular, \( \frac{a_1(x)}{a_2(x)}\) and \( \frac{a_0(x)}{a_2(x)}\) must be analytic at \(x=0\). 2. **Verifying the Regular Singular Point:** - Here, \(a_2(x) = 3x^2\), \(a_1(x) = 0\), and \(a_0(x) = \left(2x^2 + \frac{3}{4}\right)\). - We need to express \(p(x)\) and \(q(x)\): \[ p(x) = \frac{a_1(x)}{a_2(x)} = \frac{0}{3x^2} = 0 \] \[ q(x) = \frac{a_0(x)}{a_2(x)} = \frac{2x^2 + \frac{3}{4}}{3x^2} \] - Substitute in the respective boxes.3. **Finding the Indicial Equation:** - By substituting the Frobenius series \(y = \sum_{n=0}^{\infty} a_n x^{n+r}\) into the differential equation and equating coefficients of like powers of \(x\), we
