Introduction to Completing the Square Method

Completing the square is a powerful method used to solve quadratic equations. This method involves manipulating the quadratic equation to express it in a perfect square trinomial form, which can then be easily solved. In this article, we will explore how Atraeus is using the completing the square method to solve a quadratic equation.

The Quadratic Equation

The quadratic equation given to Atraeus is:

7x2−14x+6=07x^2 - 14x + 6 = 0

Step 1: Rearranging the Equation

To start solving the equation, Atraeus first rearranges it to isolate the quadratic term on one side of the equation.

7x2−14x=−67x^2 - 14x = -6

Step 2: Factoring Out the Coefficient of x2x^2

Next, Atraeus factors out the coefficient of x2x^2, which is 7.

7(x2−2x)=−67(x^2 - 2x) = -6

Step 3: Identifying the Value of AA

Now, Atraeus needs to identify the value of AA in the equation. To do this, we need to look at the coefficient of the x2x^2 term, which is 7. This coefficient is equal to the value of AA.

The Value of AA

The value of AA is equal to the coefficient of the x2x^2 term, which is 7.

Conclusion

In conclusion, Atraeus is using the completing the square method to solve a quadratic equation. By factoring out the coefficient of x2x^2, Atraeus is able to identify the value of AA as 7.

Final Answer

The final answer is 7\boxed{7}.
