Answer 2

Solving the Equation (x+3)²-x²-6x

To solve the equation (x+3)²-x²-6x, we can start by expanding and simplifying the expression.

The given equation is: (x+3)² - x² - 6x

First, let's expand and simplify the expression step by step.

Expanding (x+3)²: (x+3)² = x² + 6x + 9

Now, substituting this back into the original equation: (x+3)² - x² - 6x = (x² + 6x + 9) - x² - 6x

Simplifying the expression: (x+3)² - x² - 6x = x² + 6x + 9 - x² - 6x

Simplifying further: (x+3)² - x² - 6x = 9

So, the solution to the equation (x+3)² - x² - 6x is 9.

Conclusion

The solution to the equation (x+3)² - x² - 6x is 9.
