Question

(-3m2n+8)(5m2)
(5mn4-8m2n3+10m3n2)(2mn2)
(-6a3b2+5ab3-3)(-8a2b)

Answer 1

Explicación paso a paso:

a) (-3m2n+8)(5m2)

  (−6mn+8)×5m²

  5m²(−6mn+8)

b) (5mn4-8m2n3+10m3n2)(2mn2)

   (20mn−16mn ³+30mn²)×2mn×2

   4mn(20mn−16mn³+30mn²)

c) (-6a3b2+5ab3-3)(-8a2b)

   (−18ab²+5ab×3−3)×−8a×2b

   (−18ab²+15ab−3)×−8a×2b

  −16ab(−18ab²+15ab−3)
