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

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

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

If (a - 2b - 3c + 4d)/(a + 2b - 3c - 4d) = (a - 2b + 3c - 4d)/(a + 2b + 3c + 4d), show that : 2ad = 3bc .

If the position vector of three points are a - 2b + 3c, 2a + 3b - 4c, - 7b + 10 c, then the three points are

The vector equation to the line passing through the points a + 2b + 3c, 2a + 3b - 4c is

If 2a + 3b -c =a + 2b + c =3a -b - c then what is the ratio of a:b:c?

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