Answer 1

Explicación paso a paso:

-2 (6ab + 3ab - 5ab) + (7ab + 12ab - 5ab)

-2*4ab+(7ab+12ab-5ab)

-2 * 4ab + (14ab)

-8ab + (14ab)

R// 6ab

(6ab+3ab-5ab)+(7ab+12ab-5ab)

(4ab) + 3 (7ab + 12ab - 5ab)

(4ab) + 3 * 14ab

4ab + 42 ab

R// 45ab

(-3x²y) (4xy²) (-2x³y²)

3x²y * 4xy² * 2x³y⁴

R// 24x⁶y⁷

-20x²yz

-10xyz

-20x²

-10x

2x²

x

R// 2x

(6m + 4n) (-9m + 3n)

-6m * 9m + 6m * 3n - 4n * 9m + 4n * 3n

-54m² + 6m * 3n - 4n * 9m + 4n * 3n

-54m² + 18mn - 4n * 9m + 4n * 3n

-54m² + 18mn - 36mn + 4n * 4n

-54m² + 18mn - 36mn + 12n²

R// -54m² + 18mn + 12n²

6x² - xy - 2y² ÷ y + 2x

R// 6x² - xy - 2y + 2x
