Explanation The given differential equation is 2 x y ″ − ( 3 + 2 x ) y ′ + y = 0 (1) Consider the solution as y = ∑ n = 0 ∞ c n x n + r . Differentiating y with respect to x gives, y ′ = ∑ n = 0 ∞ ( n + r ) c n x n + r − 1 y ″ = ∑ n = 0 ∞ ( n + r ) ( n + r − 1 ) c n x n + r − 2 Use the values of y , y ′ , y ″ in equation (1) then, 2 x y ″ − ( 3 + 2 x ) y ′ + y = 0 2 x ∑ n = 0 ∞ ( n + r ) ( n + r − 1 ) c n x n + r − 2 − ( 3 + 2 x ) ∑ n = 0 ∞ ( n + r ) c n x n + r − 1 + ∑ n = 0 ∞ c n x n + r = 0 ∑ n = 0 ∞ 2 ( n + r ) ( n + r − 1 ) c n x n + r − 1 − ∑ n = 0 ∞ 3 ( n + r ) c n x n + r − 1 − ∑ n = 0 ∞ 2 ( n + r ) c n x n + r + ∑ n = 0 ∞ c n x n + r = 0 ∑ n = 0 ∞ [ 2 ( n + r ) ( n + r − 1 ) − 3 ( n + r ) ] c n x n + r − 1 − ∑ n = 0 ∞ [ 2 ( n + r ) − 1 ] c n x n + r = 0 Substitute n = k in first summation and n = k − 1 in the second summation, and then simplify ∑ k = 0 ∞ [ 2 ( k + r ) ( k + r − 1 ) − 3 ( k + r ) ] c k x k + r − 1 − ∑ k = 1 ∞ [ 2 ( k − 1 + r ) − 1 ] c k − 1 x k + r − 1 = 0 ( [ 2 ( r ) ( r − 1 ) − 3 ( r ) ] c 0 x r − 1 + ∑ k = 0 ∞ [ 2 ( k + r ) ( k + r − 1 ) − 3 ( k + r ) ] c k x k + r − 1 − ∑ k = 1 ∞ [ 2 ( k − 1 + r ) − 1 ] c k − 1 x k + r − 1 ) = 0 ( [ 2 r 2 − 5 r ] c 0 x r − 1 + ∑ k = 1 ∞ [ 2 ( k + r ) ( k + r − 1 ) c k − 3 ( k + r ) c k − 2 ( k − 1 + r ) c k − 1 + c k − 1 ] x k + r − 1 ) = 0 Thus, it gives 2 r 2 − 5 r = 0 r ( 2 r − 5 ) = 0 And 2 ( k + r ) ( k + r − 1 ) c k − 3 ( k + r ) c k − 2 ( k − 1 + r ) c k − 1 + c k − 1 = 0 On solving it gives the value of indicial roots r = 0 , 5 2
