(b + 1/2 + i*sqrt(23)/2)*(b + 1/2 - i*sqrt(23)/2)
The perfect square
Let's highlight the perfect square of the square three-member
$$\left(b^{2} + b\right) + 6$$
To do this, let's use the formula
$$a b^{2} + b^{2} + c = a \left(b + m\right)^{2} + n$$
where
$$m = \frac{b}{2 a}$$
$$n = \frac{4 a c - b^{2}}{4 a}$$
In this case
$$a = 1$$
$$b = 1$$
$$c = 6$$
Then
$$m = \frac{1}{2}$$
$$n = \frac{23}{4}$$
So,
$$\left(b + \frac{1}{2}\right)^{2} + \frac{23}{4}$$
