Completing the square is a method used to solve quadratic equations by rewriting the equation in the form ( (x - p)^2 = q ). For the equation ( 4x^2 - 8x - 5 = 0 ), we first factor out 4 from the quadratic terms to get ( 4(x^2 - 2x) - 5 = 0 ). Then, we complete the square for ( x^2 - 2x ) by adding and subtracting 1, leading to ( 4((x - 1)^2 - 1) - 5 = 0 ). This allows us to solve for ( x ) easily by isolating the squared term.

Why is the completing the square method call completing the square?
The method is called "completing the square" because it involves rearranging a quadratic equation into a perfect square trinomial. This process allows us to express the quadratic in the form ((x - p)^2 = q), where (p) and (q) are constants. By completing the square, we can easily solve for the variable and analyze the properties of the quadratic function, such as its vertex.
