    Distributive law ? difficulty with algebra!

    Hello,

    Can someone help me understand how to get from step#1 to step#2 . My algebra is rusty and its been a long time... I appreciate all the help I can get!

    Step#1
    vo = (v + d/2)(r/b + r) (1+f/a)- (v - d/2)(f/a)

    Step#2
    vo = v [(r/b + r) (1+ f/a) -(f/a)] + d(1/2) [(r/b + r) (1+ f/a) + (f/a)]

    Thank you!
