**Jai**, Thursday, May 26, 2011 at 11:38pmhow to do this: first, from the equation, we get b or the numerical coefficient of x.

from the given, b = 2.

then divide this by 2:

2/2 = 1

and square it:

1^2 = 1

thus, the number that we're looking for is 1:

x^2 + 2x + 1 =(x + 1)^2

hope this helps~ :)
