    It is instructed to subtract (2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).

    So, First we will do the sum of the three given polynomials,

    Sum =(a+3b−4c)+(4a−b+9c)+(−2b+3c−a)

    =(a+4a−a)+(3b−b−2b)+(−4c+9c+3c)

    =4a+8c

    Now, we can perform the subtraction,

    ∴ Required difference

    =(4a+8c)−(2a−3b+4c)

    =4a+8c−2a+3b−4c

    =2a+3b+4c
