x^2 - x - 6
The perfect square
Let's highlight the perfect square of the square three-member
(x2x)6\left(x^{2} - x\right) - 6
To do this, let's use the formula
ax2+bx+c=a(m+x)2+na x^{2} + b x + c = a \left(m + x\right)^{2} + n
where
m=b2am = \frac{b}{2 a}
n=4acb24an = \frac{4 a c - b^{2}}{4 a}
In this case
a=1a = 1
b=1b = -1
c=6c = -6
Then
m=12m = - \frac{1}{2}
n=254n = - \frac{25}{4}
So,
(x12)2254\left(x - \frac{1}{2}\right)^{2} - \frac{25}{4}
