Factor 30x^3y-25x^2y^2-30xy^3

$30 x^{3} y - 25 x^{2} y^{2} - 30 x y^{3}$

Step 1

Factor $5 x y$ out of $30 x^{3} y - 25 x^{2} y^{2} - 30 x y^{3}$ .

Factor $5 x y$ out of $30 x^{3} y$ .

$5 x y (6 x^{2}) - 25 x^{2} y^{2} - 30 x y^{3}$

Factor $5 x y$ out of $- 25 x^{2} y^{2}$ .

$5 x y (6 x^{2}) + 5 x y (- 5 x y) - 30 x y^{3}$

Factor $5 x y$ out of $- 30 x y^{3}$ .

$5 x y (6 x^{2}) + 5 x y (- 5 x y) + 5 x y (- 6 y^{2})$

Factor $5 x y$ out of $5 x y (6 x^{2}) + 5 x y (- 5 x y)$ .

$5 x y (6 x^{2} - 5 x y) + 5 x y (- 6 y^{2})$

Factor $5 x y$ out of $5 x y (6 x^{2} - 5 x y) + 5 x y (- 6 y^{2})$ .

$5 x y (6 x^{2} - 5 x y - 6 y^{2})$

Step 2

Factor.

Factor by grouping.

For a polynomial of the form $a x^{2} + b x + c$ , rewrite the middle term as a sum of two terms whose product is $a \cdot c = 6 \cdot - 6 = - 36$ and whose sum is $b = - 5$ .

Reorder terms.

$5 x y (6 x^{2} - 6 y^{2} - 5 x y)$

Reorder $- 6 y^{2}$ and $- 5 x y$ .

$5 x y (6 x^{2} - 5 x y - 6 y^{2})$

Factor $- 5$ out of $- 5 x y$ .

$5 x y (6 x^{2} - 5 (x y) - 6 y^{2})$

Rewrite $- 5$ as $4$ plus $- 9$

$5 x y (6 x^{2} + (4 - 9) (x y) - 6 y^{2})$

Apply the distributive property.

$5 x y (6 x^{2} + 4 (x y) - 9 (x y) - 6 y^{2})$

Remove unnecessary parentheses.

$5 x y (6 x^{2} + 4 x y - 9 (x y) - 6 y^{2})$

Remove unnecessary parentheses.

$5 x y (6 x^{2} + 4 x y - 9 x y - 6 y^{2})$

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$5 x y ((6 x^{2} + 4 x y) - 9 x y - 6 y^{2})$

Factor out the greatest common factor (GCF) from each group.

$5 x y (2 x (3 x + 2 y) - 3 y (3 x + 2 y))$

Factor the polynomial by factoring out the greatest common factor, $3 x + 2 y$ .

$5 x y ((3 x + 2 y) (2 x - 3 y))$

Remove unnecessary parentheses.

$5 x y (3 x + 2 y) (2 x - 3 y)$

Factor 30x^3y-25x^2y^2-30xy^3
