the sum of the squares of six consecutive integers is 1111. what are the integers and what is the problem solving strategy?
Let consecutive the integers be
,
,
,
,
, and
Then we have the equation:
Collect terms:
Divide through by 6:
Factor:
Use the zero factor property:
So there are two solutions:
If
, then the consecutive integers are
,
,
,
,
, and
or
,
,
,
,
, and
or
,
,
,
,
, and
and if
, then the consecutive integers are
,
,
,
,
, and
or
,
,
,
,
, and
or
,
,
,
,
, and
