Question 74125
<pre>
I have to remove the () and simplify when possible can you help me to understand?
  8d-(-7c-2d)  Dont forget that 8d-(-7c-2d) is the same as


  8d -1(-7c-2d)  Now is it clear that you have to distribute -1 to -7c and -2d?
                 by doing that you can remove ( )

  8d - 1(-7c) - 1 (-2d)  multiply 
  8d + 7c + 2d           add like terms
  10d + 7c
