$(\frac{b}{2})^{2}$
To find the term required to create a perfect square trinomial, take the coefficient of the $x$-term, divide it by two, and then square it. (This only works if the value of $a$ is $1$). $x^{2}+bx=c$ the coefficient of the $x$-term..... $b$ divide it by 2..... $(\frac{b}{2})$ and square it...... $(\frac{b}{2})^{2}$
