Question 19

Multiple Choice

The solution of the equation for the differential equation x2y′′+3xy′+y=0x ^ { 2 } y ^ { \prime \prime } + 3 x y ^ { \prime } + y = 0 is


A) y=c1x−1+c2x−1ln⁡xy = c _ { 1 } x ^ { - 1 } + c _ { 2 } x ^ { - 1 } \ln x
B) y=c1x−1+c2x−2y = c _ { 1 } x ^ { - 1 } + c _ { 2 } x ^ { - 2 }
C) y=c1x(−3+5) /2+c2x(−3−5) /2y = c _ { 1 } x ^ { ( - 3 + \sqrt { 5 } ) / 2 } + c _ { 2 } x ^ { ( - 3 - \sqrt { 5 } ) / 2 }
D) y=c1x+c2xln⁡xy = c _ { 1 } x + c _ { 2 } x \ln x
E) y=c1x+c2x2y = c _ { 1 } x + c _ { 2 } x ^ { 2 }
