Answer 2

Respuesta:

1: −3x+5xy−4−(−4y+2yx−1)+2x−3y+7

=−3x+5xy+−4+4y+−2xy+1+2x+−3y+7

Combinar términos comunes:

=−3x+5xy+−4+4y+−2xy+1+2x+−3y+7

=(5xy+−2xy)+(−3x+2x)+(4y+−3y)+(−4+1+7)

=3xy+−x+y+4

solución:

=3xy−x+y+4

2: (2x−3y)(x−4x2−5)

=(2x+−3y)(x+−4x2+−5)

=(2x)(x)+(2x)(−4x2)+(2x)(−5)+(−3y)(x)+(−3y)(−4x2)+(−3y)(−5)

=2x2−8x3−10x−3xy+12x2y+15y

=−8x3+12x2y+2x2−3xy−10x+15y

3: (−4m2)(3m−2m2+5m3)

=(−4m2)(3m+−2m2+5m3)

=(−4m2)(3m)+(−4m2)(−2m2)+(−4m2)(5m3)

=−12m3+8m4−20m5

=−20m5+8m4−12m3
