```							x – 3 = 3^2/3 + 3^1/3(x – 3)^3 = (3^2/3 + 3^1/3)^3x^3 – 27 + 27x – 9x^2 = 9 + 3 + 3*3^2/3*3^1/3(3^2/3 + 3^1/3)x^3 – 27 + 27x – 9x^2 = 12 + 9( x – 3)x^3 – 9x^2 + 18x – 27 = 12 – 27x^3 – 9x^2 + 18x – 12 = 0

```							Take x = 3+ 3^(1/3)+3^(2/3)If we are (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3This way it can be seen if we multiply 3^(1/3) with 3^(2/3) give 3So take the x-3 = 3^(1/3)+3^(2/3)Cube both side x3+27x-9x2-27 = 3+9+3*3^(5/3)+ 3*3^(4/3)=> x^3 – 27 + 27x – 9x^2 = 12 + 9( x – 3)=> x^3 – 9x^2 + 18x – 27 = 12 – 27=> x^3 – 9x^2 + 18x – 12 = 0
