Question 1177626
<br>
Formal algebra doesn't really help to solve this problem.<br>
One response you have received says form the equation and look for solutions informally.<br>
The other response says graph the equation to find the solution.<br>
Both solution methods are valid; but the formal algebra parts of the solutions didn't get you any closer to the answer  --  you still had to "look for" the answer, or get it by using a graphing utility.<br>
This problem is best solved informally from the beginning, without trying to use formal algebra.<br>
The prime factorization of 90 is 2*3*3*5.  Combine two of those factors in a way that gives you three integers that satisfy the conditions of the problem.  The way to do that is easily found: (2*3)*3*5 = 6*3*5.  6 is twice 3; and 5 is 2 more than 3.<br>
ANSWER: 3, 6, and 5<br>
