Ответ:

(a + b)² - 4  = (a + b - 2)(a + b + 2)

Объяснение:

(a + b)² - 4 = (a + b)² - 2² = (a + b - 2)(a + b + 2)

По формуле разности квадратов:

a² - b² = (a - b)(a + b)

Craig
Flatman is every nutritionist’s nightmare-a fifteen-year-old who never eats
anything except bread and jam but, unbelievably, is perfectly healthy! Although
his diet contains hardly any protein and is 60% sugar, he is 1. 84m tall,
weighs 69 kg, and his parents say he has never been seriously ill apart from
typical childhood illnesses.

Craig, or
“Jam boy”, as his friends have nicknamed him, rejects any form of meat, fish,
fresh fruit, or vegetables. The only time he doesn’t eat bread and jam is for
breakfast, when he has chocolate cereal, and for tea, when he occasionally has
a slice of chocolate cake. He also drinks two pints of semi-skimmed milk a day.

Craig’s
strange diet started when he was four years old. As a baby he had refused to
eat solid food, and rejected everything until his father gave him a sugar
sandwich when he was nine months old. He also ate chocolate spread sandwiches,
and this, with milk, was his diet until he was four when he asked to try jam,
and started an eleven-year obsession.

Craig
sometimes craves some variety, but every time he tries something else he feels
ill. Doctors believe that his condition may have been caused by choking on
solid food when he was a baby. ‘They tell me I’ll grow out of it’, says Craig,
‘but I don’t know if I’ll ever change’. Although Craig’s parents eat a normal
diet, their family meals are made more difficult by the fact that Craig’s
sister Amy, 13, is a vegetarian. And every time they go out for a meal
together, they have to phone in advance - to check they can bring jam
sandwiches for Craig.
