If a+b+c=9 and ab+bc+ca=26, find the values of a^2+b^2+c^2

Find the value of x in the tremolite abestos: Ca_(2)Mg_(x)(Si_(4)O_(11))_(2)(OH)_(2)

Find the value of x in the tremolite abestos: Ca_(2)Mg_(x)(Si_(4)O_(11))_(2)(OH)_(2)

If a^2+b^2+c^2 = 25 and a+b+c=7 , then find the value of ab+bc+ca .

Find the value of x in the tremolite abestos: Ca_(2)Mg_(x)(Si_(4)O_(11))_(2)(OH)_(2)

Prove that |(bc-a^2, ca-b^2, ab-c^2),(ca-b^2, ab-c^2, bc-a^2),(ab-c^2, bc-a^2, ca-b^2)| is divisible by a+b+c. Also find the value of the quotient.

Let a,b and c denote the sides BC,CA and AB rind the value of ABC. If |ab1ca1bc|=0 then find the value of s in^(2)A+s in^(2)B+s in^(2)C

If a,b,c are unit vectors such that a+b+c=0 , then find the value of a.b+b.c+c.a .

If a+b+c=0, then find the value of (a^(2))/(bc)+(b^(2))/(ca)+(c^(2))/(ab)
