a^(2)+b^(2)+2ab+2bc+2ca

Factorize: a^(2)+b^(2)+2(ab+bc+ca)

If a!=b!=c then prove that (a^(2)+b^(2)+c^(2))/(ab+bc+ca)>1

In triangle ABC, range of (a^(2)+b^(2)+c^(2))/(ab+bc+ca) is (a,b,c are sides of triangle)

If a,b,c are the sides ofa triangle then the expression (a^(2)+b^(2)+c^(2))/(ab+bc+ca) lies in the interval

Find the product (2a + b+c) (4a ^(2) + b ^(2) + c ^(2) - 2ab -bc -2ca)

Find the product (2a + b+c) (4a ^(2) + b ^(2) + c ^(2) - 2ab -bc -2ca)

Find the product (2a + b+c) (4a ^(2) + b ^(2) + c ^(2) - 2ab -bc -2ca)
