<font face="Times New Roman" size="+2">


Divide the coefficient on the <i>x</i> term by 2 and then square the result to obtain the constant term of the perfect square polynomial.


Because *[tex \Large (x + a)(x + a) = x^2 + 2ax + a^2].  Note that 2<i>a</i> divided by 2 is <i>a</i> and the third term of the polynomial is <i>a</i> squared.
