$a+(3a)^2-(8+a)^2+ \frac{4}{a}: \frac{2}{a^2} =a+9a^2-64-16a-a^2 +\frac{4}{a}*\frac{a^2}{2}= \\ =8a^2-64-15a +2a= 8a^2 -13a-64$

Four hundred Hebridean lobsters facing certain death were given a brief reprieve
when the plane taking them to France to become lobster pot, bisque, and
quadrille was forced to make an emergency landing behind Wormwood Scrubs
prison in the west London yesterday. The lobsters were en route from the Outer
Hebridges in Scotland to Le Touquet in northern France when the Cessna 206
light aircraft transporting them developed engine trouble. The Danish pilot, 46-
year-old Mr. Carsten Petersen, managed to guide the plane down on the land 200
yards from the Scrubs. Mr. Petersen, who lives in County Offaly in the Irish
Republic, had made earlier abortive attempts to land on Clapham Common or
Battersea Park in south London.
A spokesman for Heathrow Airport said Mr. Petersen had radioed the, saying his
plane was suffering from severe bivrating and he needed to make a speedy
landing. The airport was put on emergency alert but in the end, he was forced to
put it down in London. It seems he found some open space and had a very lucky
escape. The pilot and his cargo emerged unscathed.
'The lobsters are sick of flying,' said Mr. Petersen before dashing off to sell his
cargo at Billingsgate fish market before it died of natural causes. 'If you go into a
good London restaurant, you might get one.'
Mr. Petersen hoped his crippled aircraft would be hauled away this morning.
Scotland Yard confirmed that the plane and its lobster cargo were being treated
as an emergency landing and no charges will be brought. Residents who live
around the prison are more used to breakout dramas than forced landings.
One commented: 'Why don't they give the lobsters to the prisoners?'
