Math Problem Statement
find two positive consecutive integers such that the squares of the first, added to 3 times the second, is 24.
Solution
Let the two consecutive positive integers be and . According to the problem:
- The square of the first integer is .
- Three times the second integer is .
The sum of these two expressions is equal to 24:
Solving the equation:
-
Expand the equation:
-
Subtract 24 from both sides:
-
Solve the quadratic equation using the quadratic formula: Here, , , and . Substituting into the formula:
Since is not a perfect square, we cannot get a clean integer solution from this quadratic formula.
Checking simpler integer values:
We simplify our approach by testing small positive integers directly. Let’s test consecutive integers manually:
-
For :
- First integer squared:
- Three times the second integer:
- Sum: , not 24.
-
For :
- First integer squared:
- Three times the second integer:
- Sum: , not 24.
Thus, none of the two initial
