144 is a perfect square because 12^2 = 144
Note that 24 = 2(12).
Therefore,
x^2 - 24x + 144 = (x-12)^2

x^-24x+144=0
<=> (x - 12)^2 = 0

x^2 - 24x + 144 = (x - 12)(x - 12)
(x - 12)(x - 12) = 0
x = 12

that must be a negative number and when you add them up it equals 0 i think....... im only in 5th grade. wait a minute let me think this out.....:
144
- 24=120
count down and find the difference between 120 and 0 which is 120. so x i think is 120????? i have no idea but maybe i did it right???????!! :)

x^2-2*x*12+12^2=0
(x-12)^2=0
two coincidental roots equal to 12
