Simplifying (x+5)^2 - 10x
In mathematics, simplifying expressions is a crucial skill. This article will guide you through simplifying the expression (x+5)^2 - 10x.
Understanding the Steps
To simplify the expression, we will use the following steps:
- Expand the square: (x+5)^2 means (x+5) multiplied by itself.
- Distribute: Multiply -10x into the expanded expression.
- Combine like terms: Combine the terms with the same variable and power.
Simplifying the Expression
Let's apply these steps to our expression:
-
Expanding the square: (x+5)^2 = (x+5)(x+5) = x^2 + 5x + 5x + 25 = x^2 + 10x + 25
-
Distributing -10x: x^2 + 10x + 25 - 10x
-
Combining like terms: x^2 + (10x - 10x) + 25 = x^2 + 25
The Simplified Expression
Therefore, the simplified form of (x+5)^2 - 10x is x^2 + 25.
Conclusion
By applying the principles of expanding, distributing, and combining like terms, we have successfully simplified the given expression. This process demonstrates the power of algebraic manipulation to arrive at a more concise and manageable form.
