1)а2+аб-7а-7б= (а2-7а)+(аб-7б)=а*(а-7)+б*(а-7)=(а+б)*(а-7)
2)2х-2у+х2-ху=(2х-2у)+(х2-ху)=2*(х-у)+х*(х-у)=(х-у)*(2+х)

Прочитайте текст и выполните

задание к тексту.

1).Great Britain is situated on islands. There are seas around these islands and they

make the climate in the country very special. People often say that it rains all the

time in Britain, but it is not true. London gets no more rain a year than other big

cities in Europe. But in the west of Britain it is rainier than in the east.

Winters in Britain are not very cold. It snows but you can't often see snow in the

streets of the British cities. In the west winters are usually warmer than in the east.

Summers are not very hot. It is usually sunnier and warmer in the south than in the

north. But there can be cold days in July and some fairly warm days in January.

Britain is famous for fogs. Sometimes fogs are very thick and people can't see

anything just in front of them. English people like to talk about the weather. They

often say that Britain doesn't have a climate, it has weather. It means that the

weather is very different - rainy and dry, sunny and windy, cold and hot and all

that during one day.
