Expanding the Expression: (x + 2)(x² - 2x + 1)
This expression represents the product of a binomial and a trinomial. To simplify it, we'll use the distributive property (also known as FOIL).
The Distributive Property
The distributive property states that multiplying a sum by a number is the same as multiplying each addend by that number and then adding the products.
In our case, we need to distribute each term of the binomial (x + 2) to each term of the trinomial (x² - 2x + 1).
Expanding the Expression
-
Multiply x by each term in the trinomial:
- x * x² = x³
- x * -2x = -2x²
- x * 1 = x
-
Multiply 2 by each term in the trinomial:
- 2 * x² = 2x²
- 2 * -2x = -4x
- 2 * 1 = 2
-
Combine the results:
- x³ - 2x² + x + 2x² - 4x + 2
-
Simplify by combining like terms:
- x³ - 3x + 2
Conclusion
Therefore, the expanded form of (x + 2)(x² - 2x + 1) is x³ - 3x + 2.
