Solution :
*************************************
By algebraic identity :
(x+y+z)² = x²+y²+z²+2xy+2yz+2zx
************************************
( a/4 - b/2 + 1 )²
= [ a/4 + ( -b/2) + 1 ]²
= (a/4)²+(-b/2)²+1²+2(a/4)(-b/2)+2(-b/2)1+2(1)(a/4)
= a²/16+b²/4+1-ab/4-b+a/2

= [ a/4 + ( -b/2) + 1 ]²
= (a/4)²+(-b/2)²+1²+2(a/4)(-b/2)+2(-b/2)1+2(1)(a/4)
= a²/16+b²/4+1-ab/4-b+a/2
