(      3      +      h              )        2            −      9              (      3      +      h      )      −      3        =            (      3      +      h      )      (      3      +      h      )      −      9        h    =            (              h        2            +      6      h      +      9      )      −      9        h    =                    h        2            +      6      h        h    =    ?

You got h, because you assumed that    (  3  +  h      )    2    −  9  =  (  (  3  +  h  )  −  3  )  (  (  3  +  h  )  −  3  )But it&#039;s   (  (  3  +  h  )  −  3  )  (  (  3  +  h  )  +  3  ) After the simplification you&#039;ll get   h  +  6Important: You have to point that h is not equal to 0.
