Step-by-step explanation:

ok

Answer 2

Answer:

Step-by-step explanation:

1st $d^{4}y - d^{3}y + 2y =0$    

differetial solution:- integrate eq

$d^{3}y - d^{2}y + 2y^{2}/2 =0 +c1\\d^{2}y - dy + y^{3}/3 =c1+c2\\dy - y + y^{4}/3*4 =c1+c2+c3\\y - y^{2}/2 +y^{5}/3*4*5 = c1 + c2 + c3 + c4$

where c1,c2,c3,c4 are integration constant.
