Please Take Advantage Of My Nostalgic Moment

________________________________________________________________________________________________

Unless the sight of serious algebra
causes serious suicidal thoughts
...
...
  
Once upon a time
I called this
a JBL equation
That is,
you can solve this 
Just By Looking


 The equation has two of everything:

15 appears twice
X appears twice

There are two Plus Signs 
and there are two
square root thingies

The question is
SOLVE FOR  X

Three simple steps
is all it takes.

 ❶ Subtract 1 from 15   [=14]

Take half of that result  [=7] 

Multiply it by itself [= 49]
    
Therefore
X = 49

...
...


Regardless of what
the number is
(as long as it is an odd #)
do the same three steps:

IF
all things were the same
but the number = 11
[instead of 15]
THEN
11 ⇛ 10 ⇛ 5 ⇛ 25
