Question

x2y + 3xy – xy – 3y.

Answer 1

Answer:

A prefix is a group of letters placed before the root of a word. For example, the word “unhappy” consists of the prefix “un-” [which means “not”] combined with the root (or stem) word “happy”; the word “unhappy” means “not happy.”

Answer 2

Answer:

Hint: This is Euler-Cauchy type equation, so let:

y=xm⟹y′=mxm−1⟹y′′=m(m−1)xm−2

Substitute back into ODE, solve for roots, write the general solution and then find constants from initial conditions

y ( ×)=× ( × ^2 +3).
