Evaluate :
`[ 2a - 3b + c ]^2 - [ 2a + 3b - c ]^2`

2a - 3b - [3a - 2b - {a - c- (a - 2b)}]

The square root of (3a + 2b + 3c)^(2) - (2a + 3b + 2c)^(2) + 5b^(2) is

Simplify: 2a - [3b - {a - (2c - 3b) + 4c - 3 (a - b - 2c)}]

Subtract (2a - 3b + 4c) from the sum of (a + 3b - 4c), (4a - b +9c) and (-2b + 3c -a )

If a^2 + b^2 + c^2 = 2(a -b -c)- 3 ,then the value of (a- b + c) is यदि a^2 + b^2 + c^2 = 2(a -b -c)- 3 तो (a- b + c) का मान है-

prove that [ [a-b-c , 2a , 2a ] , [2b , b-c-a , 2b ] ,[2c ,2c,c-a-b]]= (a+b+c)^3

Evaluate the following: |[a,b,c],[a^2, b^2, c^2],[a^3, b^3, c^3]|

The value of [(a^2-b^2)^3+(b^2-c^2)^3 + (c^2-a^2)^3] div [(a-b)^3+(b-c)^3+(c-a)^3 ] is equal to: (Given a ne b ne c ) [(a^2-b^2)^3+(b^2-c^2)^3 + (c^2-a^2)^3] div [(a-b)^3+(b-c)^3+(c-a)^3 ] का मान बराबर है: ( a ne b ne c दिया)
