Step 5.3.1

Subtract $6 y x^{4}$ from both sides of the equation.

$6 x^{5} x' + 12 x^{3} x' y^{2} + 6 x x' y^{4} + 12 y^{3} x^{2} + 6 y^{5} - 16 y^{2} x x' = 16 x^{2} y - 6 y x^{4}$

$6 x^{5} x' + 12 x^{3} x' y^{2} + 6 x x' y^{4} + 6 y^{5} - 16 y^{2} x x' = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2}$

Step 5.3.3

Subtract $6 y^{5}$ from both sides of the equation.

$6 x^{5} x' + 12 x^{3} x' y^{2} + 6 x x' y^{4} - 16 y^{2} x x' = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.1

Factor $2 x x'$ out of $6 x^{5} x'$ .

$2 x x' (3 x^{4}) + 12 x^{3} x' y^{2} + 6 x x' y^{4} - 16 y^{2} x x' = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.2

Factor $2 x x'$ out of $12 x^{3} x' y^{2}$ .

$2 x x' (3 x^{4}) + 2 x x' (6 x^{2} y^{2}) + 6 x x' y^{4} - 16 y^{2} x x' = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.3

Factor $2 x x'$ out of $6 x x' y^{4}$ .

$2 x x' (3 x^{4}) + 2 x x' (6 x^{2} y^{2}) + 2 x x' (3 y^{4}) - 16 y^{2} x x' = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.4

Factor $2 x x'$ out of $- 16 y^{2} x x'$ .

$2 x x' (3 x^{4}) + 2 x x' (6 x^{2} y^{2}) + 2 x x' (3 y^{4}) + 2 x x' (- 8 y^{2}) = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.5

Factor $2 x x'$ out of $2 x x' (3 x^{4}) + 2 x x' (6 x^{2} y^{2})$ .

$2 x x' (3 x^{4} + 6 x^{2} y^{2}) + 2 x x' (3 y^{4}) + 2 x x' (- 8 y^{2}) = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.6

Factor $2 x x'$ out of $2 x x' (3 x^{4} + 6 x^{2} y^{2}) + 2 x x' (3 y^{4})$ .

$2 x x' (3 x^{4} + 6 x^{2} y^{2} + 3 y^{4}) + 2 x x' (- 8 y^{2}) = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.4.7

Factor $2 x x'$ out of $2 x x' (3 x^{4} + 6 x^{2} y^{2} + 3 y^{4}) + 2 x x' (- 8 y^{2})$ .

$2 x x' (3 x^{4} + 6 x^{2} y^{2} + 3 y^{4} - 8 y^{2}) = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$

Step 5.5

Divide each term in $2 x x' (3 x^{4} + 6 x^{2} y^{2} + 3 y^{4} - 8 y^{2}) = 16 x^{2} y - 6 y x^{4} - 12 y^{3} x^{2} - 6 y^{5}$ by $2 x (3 x^{4} + 6 x^{2} y^{2} + 3 y^{4} - 8 y^{2})$ and simplify.
