Question

Answer 1

2:

a: =(3x+1)^3

b: =(x+3y)^3

c: =(x-2y)^3

d: =(1-2x)^3

1:

a: (x+2)^3=x^3+6x^2+12x+8

b: (3x-2)^3=27x^3-54x^2+36x-8

c: (2m+5)^3=8m^3+60m^2+150m=125

d: (4a-3b)^3=64a^3-144a^2b+108ab^2-27b^3

e: (x/3-1)^3=1/27x^3-1/3x^2+x-1

f: (1/2y+4)^3=1/8y^3+3y^2+24y+64

g: (x/3+y/2)^3=1/27x^3+1/8y^3+1/6x^2y+1/4xy^2

h: (2/3x-1/5y)^3=8/27x^3-4/15x^2y+2/25xy^2-1/125y^3
