    Expanding Binomials

    Hi,

    I'm not sure how to expand binomials with negative terms, can anyone show me?

    Ex.

    1.) (a-b)^5

    2.) (4-x)^5

    3.) (t-2)^5

    4.) (m-n)^10

    Thanks!

    Do you know how to expand (A + B)^n ?

    1. Substitute n = 5, A = a and B = -b.

    2. Substitute n = 5, A = 4 and B = -x.

    3. Substitute n = 5, A = t and B = -2.

    4. Substitute n = 10, A = m and B = -n (not to be confused with n = 10).
