If `A = 3x^(2) + 5x -3 and B = 5x^(2) -7`, then `2A -B` is _____

If A = 4x ^(2) + 7x -1 and B =-x ^(2) -5x +3, then what is 3/2 A -2B ?

If A = 4x^(3) -8x^(2), B = 7x^(3) -5x + 3 and C = 3x^(3) + x - 11 , then find 2A -3B + 4C

If A = 3y^(2) + 4x - 5x^(2), B = x^(2) - 3y^(2) and C = 2x^(2) - 7xy then find A - B

If A = 4x^(3) - 5x + 7, B = 2x^(3) -x^(2) + 3 and C = 5x^(3) - 8x^(2) + 10 , then A - 2B - C is

If A = 4x^(3) - 8x^(2), B = 7x^(3) - 5x + 3 and C = 3x^(3) + x -11 , then find (A +C) - B

If A = 6x^(4) + 5x^(3) - 14x^(2) + 2x + 2 and B = 3x^(2) - 2x - 1 , then the remainder when A + B is

If A -={x//6 x ^(2)+ x-15=0}, B-={x//2x ^(2) - 5x +3 =0}and C-= {x//2x ^(2) -x-3 =0}, then A nn B nnC=

If A = 3x^2 - 4x + 1, B = 5x^2 + 3x - 8 and C = 4x^2 - 7x + 3 , then find: (i) (A + B) - C (ii) B+C -A (iii) A + B + C

If A -={x//6 x ^(2)+ x-15=0}, B-={x//2x ^(2) - 5x +3 =0}and C-= {x//2x ^(2) -x-3 =0}, then a nn B nnC=
