$2x {}^{2} + 5 xy - 3y {}^{2} )(4x - 3y)$

Answer 1

(3x² + 6x - 4) (5x + 1)

(3x²)(5x) + (3x²)(1) + (6x)(5x) + (6x)(1) + (-4)(5x) + (-4)(1)

15x³ + 3x² + 30x² + 6x - 20x - 4

15x³ + 33x² - 14x - 4  >>>Respuesta

-----------------------------------------------------------------------------

(4m² - 10m + 3) (3m - 2)

(4m²)(3m) + (4m²)(-2) + (-10m)(3m) + (-10m)(-2) + (3)(3m) + (3)(-2)

12m³ - 8m² - 30m² + 20m + 9m - 6

12m³ - 38m² + 29m - 6 >>>Respuesta

--------------------------------------------------------------------------------------------------

(2b³ - 2b² + 4b - 5) (3b² + 5b - 2)

6b⁵ + 4b⁴ - 2b³ + 9b² - 33b + 10 >>>Respuesta

------------------------------------------------------

(3b² - 2b + 10) (-5b - b + 1)

(3b²)(-5b) + (3b²)(-b) + (3b²)(1) + (-2b)(-5b) + (-2b)(-b) + (-2b)(1) + (10)(-5b) + (10)(-b) + (10)(1)

-15b³ - 3b³ + 3b² + 10b² + 2b² - 2b - 50b - 10b + 10

-18b³ + 15b² - 62b + 10 >>>Respuesta

--------------------------------------------------------------------

(2a - 3b) (3a² - 2ab - b²)

(2a)(3a²) + (2a)(-2ab) + (2a)(-b²) + (-3b)(3a²) + (-3b)(-2ab) + (-3b)(-b²)

6a³ - 4a²b - 2ab² - 9a²b + 6ab² + 3b³

6a³ - 13a²b + 4ab² + 3b³ >>>Respuesta

--------------------------------------------------------------------------------------------------------

(2x² + 5xy - 3y²) (4x - 3y)

(2x²)(4x) + (2x²)(-3y) + (5xy)(4x) + (5xy)(-3y) + (-3y²)(4x) + (3y²)(-3y)

8x³ - 6x²y + 20x²y - 15xy² - 12xy² - 9y³

8x³ + 14x²y - 27xy² - 9y³ >>>>Respuesta

-------------------------------------------------------------------

eso es todo , espero se entienda xD

SALUDOS!!
