Math Problem Statement
find two positive consecutive integers such that the square of first, added three times the second is 24.
Solution
Let's define the two consecutive integers as and .
According to the problem, the square of the first integer, added to three times the second integer, equals 24. This can be expressed as the following equation:
Step 1: Expand and simplify the equation
Step 2: Subtract 24 from both sides to set the equation equal to zero:
Step 3: Solve the quadratic equation
We can solve this quadratic equation using the quadratic formula:
Here, , , and .
Substitute these values into the quadratic formula:
Step 4: Approximate the square root
The square root of 93 is approximately , so:
Step 5: Solve for
Since we are looking for positive integers, we discard these values because is not an integer. There is no integer solution to this quadratic equation that meets the requirements.
Thus, the problem as stated does not have a solution for positive consecutive integers.
