Question

(3a^2 b+4ab^2) MULTIPLICAR POR (a^2 b-2ab^2-10b^3)

Ayuda!!

Answer 1

Respuesta:

$3 {a}^{4} {b}^{2} - 2 {a}^{3} {b}^{3} - 38 {a}^{2} {b}^{4} - 40a {b}^{5}$

Explicación paso a paso:

${a}^{2} b - 2a {b}^{2} - 10 {b}^{3} \\ \times 3 {a}^{2} b + 4a {b}^{2}$

______________________________________

$3 {a}^{4} {b}^{2} - 6 {a}^{3} {b}^{3} - 30 {a}^{2} {b}^{4} \\ + 4 {a}^{3} {b}^{3} - 8 {a}^{2} {b}^{2} - 40a {b}^{5}$

_______________________________________

$3 {a}^{4} {b}^{2} - 2 {a}^{3} {b}^{3} - 38 {a}^{2} {b}^{4} - 40a {b}^{5}$

Espero te sirva
