$18 x^{3} y^{2} - 8 x^{2} y^{4} + 20 x y^{3}$

Etapa 1

Reordene $18 x^{3} y^{2}$ e $- 8 x^{2} y^{4}$ .

$- 8 x^{2} y^{4} + 18 x^{3} y^{2} + 20 x y^{3}$

Etapa 2

Fatore $- 2 x y^{2}$ de $- 8 x^{2} y^{4}$ .

$- 2 x y^{2} (4 x y^{2}) + 18 x^{3} y^{2} + 20 x y^{3}$

Etapa 3

Fatore $- 2 x y^{2}$ de $18 x^{3} y^{2}$ .

$- 2 x y^{2} (4 x y^{2}) - 2 x y^{2} (- 9 x^{2}) + 20 x y^{3}$

Etapa 4

Fatore $- 2 x y^{2}$ de $20 x y^{3}$ .

$- 2 x y^{2} (4 x y^{2}) - 2 x y^{2} (- 9 x^{2}) - 2 x y^{2} (- 10 y)$

Etapa 5

Fatore $- 2 x y^{2}$ de $- 2 x y^{2} (4 x y^{2}) - 2 x y^{2} (- 9 x^{2})$ .

$- 2 x y^{2} (4 x y^{2} - 9 x^{2}) - 2 x y^{2} (- 10 y)$

Etapa 6

Fatore $- 2 x y^{2}$ de $- 2 x y^{2} (4 x y^{2} - 9 x^{2}) - 2 x y^{2} (- 10 y)$ .

$- 2 x y^{2} (4 x y^{2} - 9 x^{2} - 10 y)$
