★☆☆☆☆ Level 1 of 5
Find all positive integer pairs \((x,y)\) such that \(xy=12\).
List the positive divisors of \(12\).
The positive divisors of \(12\) are \(1,2,3,4,6,12\). Thus the pairs are \((1,12),(2,6),(3,4),(4,3),(6,2),(12,1)\).
This elementary problem prepares for transformations of the form \((x-a)(y-b)=N\).
