X³-3x²-4x+12=0(х³-3х²)-(4х-12)=х²(х-3)-4(х-3)==(х-3)(х²-4)=(х-3)(х-2)(х+2)=0.х₁=-2,х₂=2,х₃=3

Помогите, пожалуйста с переводом текста.
Cambridge is situated at a distance of 70 miles from London; the great part of the town lies on the left bank of the river Cam. Cambridge is one of the most beautiful towns of England. It is not a modern industrial city and looks a country town. It is very green with a number of beautiful groupings of architecture, trees, gardens, lawns and bridges. The main building material is stone. Cambridge University is known all over the world. It is a centre of education and learning. Newton, Byron, Darwin, Rutherford and many other scientists and writers were educated in Cambridge. In Cambridge everything is centered on the University and its colleges the eldest of which was founded in 1284. They are twenty seven in number. There is a close connection between the University and colleges, though they are quite separate in theory and practice. The college is a place where you live. The students studying literature and the students trained for physics may belong to the one and the same college. You are to be a member of a college in order to be a member of the University. Every college is headed by a dean. Proctors and numerous minor officials called bulldogs look after discipline. A college is a group of buildings which forms a square with a green lawn in the centre. An old tradition does not allow the students to walk on the grass: this is the privilege of professors and head students only. There is another tradition which the students are to follow: after sunset they are not allowed to go out without a black cap and a black coat. The University existed before the colleges. It has the power to grant degrees, it defines courses of study, and organizes most of the formal teaching. Professors and lecturers provide the teaching. The University trains 7000 students of different specialities. Each student studies at the University for 4 years, three terms a year. He is trained by a tutor; each tutor has 10-12 students. The long vacation lasts three months.
