​

Respuesta :

Answer:

The element you add is      [tex]b^2 / 4a[/tex]

Step-by-step explanation:

The element you add is      [tex]b^2 / 4a[/tex]

Remember that

[tex]a x^2 + bx +c \\= a ( x^2 +(b/a)x ) + c[/tex]

So, in order to complete the square you add   [tex](b/2a)^2[/tex]

But when you multiply times  [tex]a[/tex]   you get

[tex]b^2 / 4a[/tex]
