Find the value of a so that the differential equation y ' − xy − 6x = 0 has a solution of the form y(x) = a + bex2/2 for any con

SVEN [57.7K]

Hello,

$y=a+be^\frac{ x^{2} }{2} \\\\

y'=a'+b*x*e^\frac{ x^{2} }{2} \\\\

y'-xy-6x=0\\\\

a'+b*x*e^\frac{ x^{2} }{2}-b*x*e^\frac{ x^{2} }{2}-ax-6x=0\\\\

a'=x(a+6)\\\\

 \dfrac{a'}{a+6} =x\\\\

ln (a+6)= \dfrac{x^2}{2} +c\\\\

a=k*e^\frac{ x^{2} }{2}-6\\\\
