    distributive property

    Hello guys i hv a doubt, the only distributive property i know in Linear Algebra is: A(C+B) = AC+BC

    I wan to know if (A+B).(A-B) =
    aČ-bČ is valid

    But the matrix A is order 4x2 and the matrix B order 2x4

    None of that is valid. You cannot even add A_{4\times 2}+B_{2\times 4}~!
