Have a nice day
Step-by-step explanation:

First, let's move the
to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:

From here, since the coefficient of the
term is
, we know the square will be
(since
it's half of
).
To complete this square, we will need to add
to both sides of the equation:



Now we can take the square root of both sides to figure out the solutions to
:


The sum is of n and 14 can be written as:
n+14=72
