**Steps:**

**1) TRANSFORM the differential equation to the form: **

$$\frac{dy}{dx} = f \left( x,y \right)$$

**2) Test for Linear form: **

$$f \left( x,y \right) = g \left( x \right) y + h \left( x \right)$$

**3) Test for Bernoulli equation: **

$$f \left( x,y \right) = g \left( x \right) y + h \left( x \right) y^{a}$$

**4) Test for Variable separable: **

$$f \left( x,y \right) = g \left( x \right) h \left( y \right)$$

**5) Test for Homogeneity: **

$$f \left( x,y \right) = f \left( tx, ty \right)$$

**6) Test for Exactness**
