(a+b) (a-b)=2013+b²
a+b=2013 or a-b=2013
a=2013-b or 2013+b
so b is equal to zero
Because 0 is the only number that can sum and reduce without changing the values.
a*b=0
a+b=2013 or a-b=2013
a=2013-b or 2013+b
so b is equal to zero
Because 0 is the only number that can sum and reduce without changing the values.
a*b=0
