Answer:
2\sqrt{x}+\frac{1}{2\sqrt{x}}\left(2x+3\right)
Step-by-step explanation:
which is D on your phone
Answer: sin 33° and cos 57°
Step-by-step explanation:
Let

. Then

and

are two fundamental, linearly independent solution that satisfy


Note that

, so that

. Adding

doesn't change this, since

.
So if we suppose

then substituting

would give

To make sure everything cancels out, multiply the second degree term by

, so that

Then if

, we get

as desired. So one possible ODE would be

(See "Euler-Cauchy equation" for more info)
The answer is 3, since 3*3*3 equals 27
