Best answer 1 votes 1 votes a2 = b+c b2 = a+c c2 =a+ b a+a2 = a+ b+c =a(1+a) b+b2 = a+b+c =b(1+b)c+c2 =a+ b +c=c(1+c) So: (1/1+a)+(1/1+b)+(1/1+c)=a/(a+b+c) + b/(a+b+c)+c/(a+b+c) =(a+b+c)/(a+b+c) =1 Purple answered Jan 29, 2016 selected Jan 29, 2016 by shivanisrivarshini Purple comment Share Follow See all 0 reply Please log in or register to add a comment.
