Solve:- `(a - b - c)^3`.

Simplify : (a - 2b + c)^3 - (a - 2b)^3 - 3c ( a - 2b +c)(a - 2b)

Solve : |(x + a, b, c),(a, x+b, c),(a, b, x + c)| =0

Solve. ( c) 22.50 × 3.50

Solve (b) 3.75 × 8 - 2.50 × 3

If a/b = b/c = c/d , then show that (a - b)^(3) : (b - c)^(3) = a : d .

If b/(a + b) = (3a - c - b)/(2b + c -a) = (-a+3c)/(2a - b + 3c) ( "where " a + b + c ne 0) , then prove that a = b = c .

If a, b, c are in GP then prove that a^3, b^3, c^3 are in GP.

If a prop b and b prop c , then prove that a^3 + b^3 + c^3 prop 3abc .

Let's write the value of (a + b + c) by calculation if a^3 + b^3 + c^3 = 3abc (a ne b ne c).

If a b+b c+c a=0, then solve a(b-2c)x^2+b(c-2a)x+c(a-2b)=0.
