Let ( x ) be the first positive integer. Then, the next consecutive positive integer is ( x + 1 ). According to the given condition, we have the equation ( x(2(x + 1)) = 612 ).
Expanding and simplifying:
( x(2x + 2) = 612 )
( 2x^2 + 2x = 612 )
Divide both sides by 2:
( x^2 + x = 306 )
Rearrange the equation:
( x^2 + x - 306 = 0 )
Now, we can use the quadratic formula to solve for ( x ):
( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} )
Where ( a = 1 ), ( b = 1 ), and ( c = -306 ).
( x = \frac{-1 \pm \sqrt{1^2 - 4(1)(-306)}}{2(1)} )
( x = \frac{-1 \pm \sqrt{1 + 1224}}{2} )
( x = \frac{-1 \pm \sqrt{1225}}{2} )
( x = \frac{-1 \pm 35}{2} )
Since ( x ) must be positive, we take the positive root:
( x = \frac{-1 + 35}{2} = \frac{34}{2} = 17 )
So, the first positive integer is 17, and the next consecutive positive integer is ( 17 + 1 = 18 ).
Therefore, the sum of these two integers is ( 17 + 18 = 35 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
