Question 1146488
.
<pre>
Let x be the second number.


Then the first number is (2x+2).


The condition says


    x*(2x+2) = 24.


Simplify and solve for x


    x*(x+1) = 12.


The two solutions for x are obvious:  x= 3  and  x= -4.


It gives two pairs of the numbers, the problem asks for:


    one pair is        (2*3+2,3)     = (8,3);


    the other pair is  (2*(-4)+2,-4) = (-6,-4).
</pre>

Solved.

The lesson to learn from my post is <U>THIS</U> :


<pre>
    When you "guess", be careful :  guessing does not guarantee that you get all solutions.


    Algebra guarantees (when it works . . . )
