x2 - 10x + _ "find value that completes the square and rewrite as perfect square" what does it mean by "rewrite as perfect square"

Respuesta :

A perfect square is something times that same thing. Example (x+2)(x+2)

The reason it's called a perfect square is because it can be re-written as a squared function:

[tex] (x+2)(x+2) = (x+2)^{2} [/tex]
In the blank is 25
Half of 10 is 5 and 5^2= 25
