Understanding (x + 6)^2
The expression (x + 6)^2 represents the square of the binomial (x + 6). This means we're multiplying the binomial by itself.
Here's how to expand and simplify it:
-
Write out the multiplication: (x + 6)^2 = (x + 6)(x + 6)
-
Apply the distributive property (FOIL):
- First: x * x = x^2
- Outer: x * 6 = 6x
- Inner: 6 * x = 6x
- Last: 6 * 6 = 36
-
Combine like terms: x^2 + 6x + 6x + 36 = x^2 + 12x + 36
Therefore, the expanded form of (x + 6)^2 is x^2 + 12x + 36.
Key Points to Remember:
- Squaring a binomial: Always remember to multiply the binomial by itself.
- FOIL method: A useful tool for expanding binomials.
- Combining like terms: Essential for simplifying the final expression.
Understanding the expansion of (x + 6)^2 is crucial for various algebraic operations and solving equations.
