$\frac{2 x^{3} - 15 y^{3} + 7 x^{2} y - 4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$

Step 1

Split the fraction $\frac{2 x^{3} - 15 y^{3} + 7 x^{2} y - 4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$ into two fractions.

$\frac{2 x^{3} - 15 y^{3} + 7 x^{2} y}{x^{2} + 2 x y - 5 y^{2}} + \frac{- 4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$

Step 2

Split the fraction $\frac{2 x^{3} - 15 y^{3} + 7 x^{2} y}{x^{2} + 2 x y - 5 y^{2}}$ into two fractions.

$\frac{2 x^{3} - 15 y^{3}}{x^{2} + 2 x y - 5 y^{2}} + \frac{7 x^{2} y}{x^{2} + 2 x y - 5 y^{2}} + \frac{- 4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$

Step 3

Split the fraction $\frac{2 x^{3} - 15 y^{3}}{x^{2} + 2 x y - 5 y^{2}}$ into two fractions.

$\frac{2 x^{3}}{x^{2} + 2 x y - 5 y^{2}} + \frac{- 15 y^{3}}{x^{2} + 2 x y - 5 y^{2}} + \frac{7 x^{2} y}{x^{2} + 2 x y - 5 y^{2}} + \frac{- 4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$

Step 4

Move the negative in front of the fraction.

$\frac{2 x^{3}}{x^{2} + 2 x y - 5 y^{2}} - \frac{15 y^{3}}{x^{2} + 2 x y - 5 y^{2}} + \frac{7 x^{2} y}{x^{2} + 2 x y - 5 y^{2}} + \frac{- 4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$

Step 5

Move the negative in front of the fraction.

$\frac{2 x^{3}}{x^{2} + 2 x y - 5 y^{2}} - \frac{15 y^{3}}{x^{2} + 2 x y - 5 y^{2}} + \frac{7 x^{2} y}{x^{2} + 2 x y - 5 y^{2}} - \frac{4 x y^{2}}{x^{2} + 2 x y - 5 y^{2}}$
