The perfect square 
can be expanded as follows:
So, we have to think of the term 
as 
, which implies 
.
Thus, we have to add 
, i.e. 16, to complete the perfect square:
Imagine that the variable c represents something tangible, like an orange. So what this equation is asking is subtract 1 orange from 12 oranges. So you are left with 11 oranges.
Another way to think about this problem is if you rewrite the equation slightly to:
12c - c =
12c - 1c =
11c
If y
y
varies directly as x
x
and y=15
y
=
15
when x=24
x
=
24
, find x
x
when y=25
y
=
25
.
Find the constant of variation.
k=yx=1524=58y=58x k=

To find x

for y
y
