    Very quick question about Binomial Theorem

    I just need to clarify this; when you are asked to find the coefficient of a certain x power, is it necessary to indicate the negative or positive sign? What about when finding the term independent of x? Thanks, I just got a little confused.

    Simple Circle Geometry question

    Draw it from my explanation if you can: AMB and CMB are two intersecting chords of a circle, centre O. If OM bisects angle AMC internally, prove that AB = CB. I tried by proving congruent triangles ADM and CMB, but it didn't work lol. Thanks to whoever can help. :)
