One integer is 2 times another.
if one integer is x, the other integer y, than
x=2y.......eq.1
If the product of the two integers is 98, than
xy=98.......eq.1..substitute x=2y
2y%2Ay=98
2y%5E2=98
y%5E2=98%2F2
y%5E2=49
y=sqrt%2849%29
so, y=7 or y=-7
then,
x=2y->x=2%2A7->x=14 or
x=2y->x=2%2A%28-7%29->x=-14
solutions:
integers are:
14 and 7
or
-14 and -7
