Expanding the Expression (x+6)(x+2)
In mathematics, expanding an expression means writing it in a simpler form without parentheses. Here's how to expand the expression (x+6)(x+2):
Using the FOIL Method
The FOIL method is a common technique for expanding binomials (expressions with two terms). It stands for First, Outer, Inner, Last. Here's how it works:
- First: Multiply the first terms of each binomial: x * x = x²
- Outer: Multiply the outer terms of the binomials: x * 2 = 2x
- Inner: Multiply the inner terms of the binomials: 6 * x = 6x
- Last: Multiply the last terms of each binomial: 6 * 2 = 12
Now, combine the terms: x² + 2x + 6x + 12
Finally, simplify by combining like terms: x² + 8x + 12
Therefore, the expanded form of (x+6)(x+2) is x² + 8x + 12.
Alternative Method - Distributive Property
You can also expand the expression using the distributive property. This method involves distributing each term of the first binomial over the second binomial:
- x * (x+2) = x² + 2x
- 6 * (x+2) = 6x + 12
Now, combine the results from both steps: x² + 2x + 6x + 12
Finally, simplify by combining like terms: x² + 8x + 12
Conclusion
Both the FOIL method and the distributive property lead to the same simplified form: x² + 8x + 12. Choose whichever method you find easier and more comfortable to apply.
