Completing the square:
vichka [17]

Answer:

Step-by-step explanation:

Key to this method is remembering that

(a+b)^2 = a^2 + 2ab + b^2

So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.

6/2 = 3, so add 3^2 = 9

x^2+6x+9 = (x+3)^2

So, c=9

Similarly, for the other two,

c = (\frac{-34}{2} )^2 = (-17)^2 = 289

You don't really have to worry about the sign, since squaring will always make it positive

(\frac{25}{13}) ^2 = \frac{625}{169}
