Answer 1

Respuesta:

(3)(-2)(-5)(-4)= -120

2(3+5)-4(5+2)= -12

3xy(2x+11y-4z)=  6x∧2y+33xy∧2-12xyz

x^2 y^3 (-5x-3xy-12y)=  96x∧3y∧4

(4x+3)(2x-5)=  8x∧2-14x-15

(7a+2b)(5a-8b)=  35a∧2-46ab-16b∧2

(2m+3n)(5m-4n)=  10m∧2+7mn-12n∧2

(x+2y+z)(5x-3y-z)=  5x∧2+7xy+4xz-6∧2-5yz-z2

(x^2+x+2)(2x^2+5x-1)=  2x∧4+7x∧3+8x∧2+9x-2

(4m^2+2m-3)(m^2+6m-2)=  4m∧4+26m∧3+m∧2-22m+6

Explicación paso a paso: la explicación sería demasiada larga espero te sirva:)
