Math Problem Statement
the sum of the squares of three consecutive integers is 110. Find the integers
Solution
Let the three consecutive integers be represented as , , and .
The sum of the squares of these integers is given as 110, so we set up the equation:
Expanding each square term, we get:
Substituting these into the equation, we have:
Simplify by combining like terms:
Subtract 2 from both sides:
Now, divide by 3:
Take the square root of both sides:
Case 1:
The three consecutive integers are , , and .
Case 2:
The three consecutive integers are , , and .
Thus, the two possible sets of integers are:
