The expression `(a+b+c)(b+c-a)(c+a-b)(a+b-c)`
`lekb^(2)c^(2)` then k can take the value

The expression : ((a+b+c)(b+c-a)(c+a-b)(a+b-c))/(4b^(2)c^(2)) is :

The expression ((a+b+c)(b+c-a)(c+a-b)(a+b-c))/(4b^2 c^2) for a triangle ABC is equal to

If the expression a(b-c)x^(2)+b(c-a)xy+c(a-b)y^(2) is a perfect square, then a,b,c are in

If a,b,c are the sides of triangle then (a)/(c +a -b) + (b)/(a +b -c) + (c )/(b +c-a) can take vlaue (s)

The expression (a-b)^(3)+(b-c)^(3)+(c-a)^(3) can be factorized as (a)(a-b)(b-c)(c-a)(b)3(a-b)(b-c)(c-a)(c)-3(a-b)(b-c)(c-a)(d)(a+b+c)(a^(2)+b^(2)+c^(2)-ab-bc-ca)

If |(a-b-c, 2a, 2a),(2b, b-a-c, 2b),(2c, 2c, c-a-b)|=(a+b+c)(x+a+b+c^2) then thhe value of x is equal to (A) -2(a+b+c) (B) a+b+c (C) -(a+b+c) (D) 2(a+b+c)

Value of the expression ((a-b)^(2))/((b-c) (c-a)) +((b-c)^(2))/((a-b) (c-a)) +((c-a)^(2))/((a-b) (b-c)) is
