the problem is about adding and subtracting polynomials...

This is what I did...




but then, if I add both 5x+4+4x+15

    I think this deals with the same problem you posted at 8:49 pm

    In this question I think you wanted to subract 5x+4 from 9x+11

    that would be 9x+11 - (5x+4)
    = 9x + 11 - 5x - 4
    = 4x + 7

    See how important brackets and the order of operations are ??
