Ayuda polinomios suma y resta y multiplicación doy estrellaaa ayudaaaa​

Answer 1

- (3x-8y+12) (5x+4y)

3x(5x+4y) - 8y (5x+4y) + 12 (5x+4y)

15

$15{x}^{2} \: + 12xy \: - 40xy \: - 32 {y}^{2} + 60x + 48y$

$15 {x}^{2} - 28xy - 32 {y}^{2} + 60x + 48y$

-(6x-6y-10) + (-2x-9y-4)

6x-6y-10-2x-9y-4

4x-15y-14

-(7x-5y) (6x+9y)

7x(6x+9y) - 5y(6x+9y)

${42x}^{2} + 63xy - 30xy - {45y}^{2}$

${42x}^{2} + 33xy - {45y}^{2}$
