Step 1:

\

The differential equation is $\"\"$ .

\

$\"\"$ .

\

Apply integration on each side.

\

$\"\"$

\

Use the power rule property: $\"\"$ .

\

$\"\"$

\

Consider $\"\"$ .

\

Differentiate on each side with respect to $\"\"$ .

\

$\"\"$

\

Use the power rule of differentiation : $\"\"$ .

\

Use the constant rule of differentiation: $\"\"$ .

\

$\"\"$

\

Step 2:

\

$\"\"$

\

Consider $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .

\

$\"\"$

\

Use the power rule of differentiation : $\"\"$ .

\

$\"\"$

\

Hence,

\

$\"\"$

\

Substitute $\"\"$ in $\"\"$ .

\

$\"\"$ .

\

$\"\"$ .

\

solution :

\

$\"\"$ .
