3 **Differential Equation Singular Points Analysis****Problem Statement:**Determine all the singular points of the given differential equation:\[(t^2 - 2t - 3)x'' + (t + 1)x' - (t - 3)x = 0\]**Question:**Select the correct choice from below and, if necessary, fill in the answer box to complete your choice.**Choices:**- **A.** The singular points are all \( t \leq\) [Blank] - **B.** The singular points are all \( t \leq\) [Blank] and \( t =\) [Blank] *(Use a comma to separate answers as needed.)*- **C.** The singular point(s) is/are \( t =\) [Blank] *(Use a comma to separate answers as needed.)*- **D.** The singular points are all \( t \geq\) [Blank] and \( t =\) [Blank] *(Use a comma to separate answers as needed.)*- **E.** The singular points are all \( t \geq\) [Blank]- **F.** There are no singular points.**Explanation:**To identify singular points, we check where the coefficients of the highest derivative or leading terms of the equation become zero or undefined. For the given equation, we focus on the coefficient of the second derivative (\(x''\)), which is \(t^2 - 2t - 3\). Finding the roots of this quadratic will help identify potential singular points.
