If `a, b, c in R` and `(a + b + c) c< 0` then the quadratic equation `p(x) = ax^2 + bx + c = 0` has :

Let set A=(a, b, c, d) and R= {(a, b), (b, c). (c, d)} is a relation on set A. The minimum number of ordered pairs which should be added into R to make it an equivalence relation on set A is

Let a = {a, b, c} and R = {(a, a), (b, b), (c, c), (b, c), (a, b)} be a relation on A, then the

Let a = {a, b, c} and R = {(a, a), (b, b), (c, c), (b, c), (a, b)} be a relation on A, then the

If A = {a, b, c} and R = {(a, a), (a, b), (b, b), (c. c),(c. a)} is a binary relation on A, then which one of the following is correct?

If a ,b ,c in R^+, t h e n(b c)/(b+c)+(a c)/(a+c)+(a b)/(a+b) is always

If a,b,c in R^(+) then b(c)/(b+c)+a(c)/(a+c)+a(b)/(a+b) is always

If a,b,c in R^(+), then (bc)/(b+c)+(ac)/(a+c)+(ab)/(a+b) is always (a) (a) =(1)/(3)sqrt(abc)(c) =(1)/(2)sqrt(abc)

If In (a+c),ln(a-c),ln(a-2b+c) are in AdotPdot, then a , b , c ,a r einAdotPdot (b) a^2,b^2,c^2a r einAdotPdot a , b , c are in GdotPdot (d) a , b , c are in HdotPdot

If In(a+c),ln(a-c),ln(a-2b+c) are in AdotPdot, then a , b , c ,a r einAdotPdot (b) a^2,b^2,c^2a r einAdotPdot a , b , c are in GdotPdot (d) a , b , c are in HdotPdot
