Simplify (x-1)^3

Problem

(x−1)3

Solution

1. Identify the expression as a binomial cube of the form (a−b)3

2. Apply the formula for the cube of a binomial, which is (a−b)3=a3−3*a2*b+3*a*b2−b3

3. Substitute a=x and b=1 into the formula.

4. Expand the terms: x3−3*(x2)*(1)+3*(x)*(1)−1

5. Simplify each term to reach the final polynomial form.

Final Answer

(x−1)3=x3−3*x2+3*x−1
