Question

The expansion form of (x+1/3) whole cube

Answer 1

Answer:

3.375x^3 + 6.75x^2+ 4.5x +1

Step-by-step explanation:

2x+1)}^3 = 1 (say)

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

27 = (2x+1)^3

27 = 8x^3 + 1 + 6x(2x+1) {(a+b)^3 = a^3 + b^3 + 3ab(a+b) }

27 = 8x^3 + 1 + 12x^2 + 6x

26 = 8x^3 + 12x^2 + 6x

8x^3 + 12x^2 + 6x - 26 = 0
