Answer 1

1. (3x+1)^3 = (3x)^3 + 3(3x)^2(1) + 3(3x)(1)^2 + (1)^3

(3x+1)^3 = 27x^3 + 27x^2 + 9x + 1

2. (2x+3)^3 = (2x)^3 + 3(2x)^2(3) + 3(2x)(3)^2 + (3)^3

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

3. (2x-1)^3 = (2x)^3 - 3(2x)^2(1) + 3(2x)(1)^2 - (1)^3

(2x-1)^3 = 8x^3 - 12x^2 + 6x - 1

4. (3x-5)^3 = (3x)^3 - 3(3x)^2(5) + 3(3x)(5)^2 - (5)^3

(3x-5)^3 = 27x^3 - 135x^2 + 225x - 125

5. (4x-y)^3 = (4x)^3 - 3(4x)^2(y) + 3(4xy)^2 - (y)^3

(4x-y)^3 = 64x^3 - 48x^2y + 12xy^2 - y^3
