You can put this solution on YOUR website! REMEMBER F O I L ----->>>>> FIRST, OUTSIDE, INSIDE, AND LAST!!!! MULTIPLYING YOUR FIRST TWO TERMS GIVES YOU 25X^2, MULTIPLING THE OUTSIDE AND INSIDE TERMS AND THEN ADDING THEM GIVES YOU A ZERO, AND THEN MULTIPLYING THE LAST TERMS GIVES YOU -3Y^2. SO YOUR ANSWER IS 25X^2 - 3Y^2. I HOPE THIS HELPS YOU!? E - MAIL ME ANY TIME FOR MORE HELP. cats7051@yahoo.com YOUR MATH FRIEND, TERRY :)
