Answer 1

(x+3)^3
(x)^3+3(x)^2(3)+3(x)(3)^2+(3)^3
x^3+3x^2(3)+3x(9)+27
x^3+9x^2+27x+27

(9+y)^3
(9)^3+3(9)^2(y)+3(9)(y)^2+(y)^3
729+3(81)(y)+27y^2+y^3
729+243y+27y^2+y^3

(3x+2)^3
(3x)^3+3(3x)^3(2)+3(x)(2)^2+(2)^3
9x^3+3(27x^3)(2)+

Answer 2

(x+3)³ = x²+6x+9                                                                                               (9+y)³ = 729+243y+27y²+y³
(3x+2)³ = 27x³+54x²+36x+4
(x+4)³ = x³+12x²+48x+16
(x⁴+1)³ = x^12+3x^8+3x^4+1
(y-x)³ = y³-3y²x+3yx²-x³
(a-2)³ = a³-6a²+12a-4
(2x-1)³ = 8x³-12x²+6x-1
(x-y³)³ = x³-3x²y³+3xy^6-y^9
(3-4a²)³ = 27-108x²+36a⁴-4a⁶
