How Do You Expand \( (x-2)^3 \)?

You can Expand \( (x-2)^3 \) through formulas and simple multiplication method.

I am going to expand \( (x-2)^3 \) through the formula.

=> \(  (a-b)^3 = a^3  + 3ab^2 – 3ba^2 -b^3 \)

=> \( (x-2)^3 = x^3  + 3x \times 2^2 – 3\times 2 x^2 -2^3 \)

=> \( (x-2)^3 = x^3  + 3x \times 4 – 3\times 2 x^2 -8 \)

=> \( (x-2)^3 = x^3  + 12x  – 6x^2 -8 \)

=> \( (x-2)^3 = x^3 – 6x^2 +   12x -8 \)
