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.
=> \( (a-b)^3 = a^3 + 3ab^2 – 3ba^2 -b^3 \)
=> \( (x-2)^3 = x^3 + 3x \times 2^2 – 3\times 2 x^2 -2^3 \)
=> \( (x-2)^3 = x^3 + 3x \times 4 – 3\times 2 x^2 -8 \)
=> \( (x-2)^3 = x^3 + 12x – 6x^2 -8 \)
=> \( (x-2)^3 = x^3 – 6x^2 + 12x -8 \)
