    Let V be the vector space of all 2 x 2 matrices over the field R of re...
    Let U (F) and V(F) be two vector spaces and let T be a linear transformation from U to V, then the null space of T written as N(T) is the set of all vectors a in U such that T(α) = Of zero vector of V)

    The null space of T is also called the kernel of T.
    Now the standard basis for a vector space of all 2x2 matrices over field R of real number is {e1, e2, e3, e4}
    where

    we have, T(A) = AB - BA, where B = 
    so,

    Thus. T (e1), T(e2), T(e3) and T(e4) span the range of T 
    Null space
    let  ∈ null space of T

    This system of equations have two independent variables hence, it have two independent solutions.
    ⇒ The dimension of null space is 2.
