- Hi,
- Can any one respond me to the following problem.
-
- A , B ,C ,D belong to { ....,-2,-1,0,1,2,... }
-
- and A is always greater than 1.
-
- a , b , c belong to { -1, 0 , 1}.
-
- (A + B + C - a - b -c) ( a + b + c) greater than or equal to 0 and
-
- (A - B + D - a + b) ( a - b ) greater than or equal to 0 and
-
- (A - C - D - a + c) ( a - c ) greater than or equal to 0 and
-
- (-C + B + D - b + c) ( b - c ) greater than or equal to 0
-
- Can you show that B, C, D cover the whole integer space while A>1
-
- and a, b, c in {-1, 0 ,1}.
-
- I thank you in anticipation.
