так как квадратное уравнение приведённое, то произведение корней можно найти по теорме Виета.

если x^2+px+q=0, то x₁*x₂=q.

тогда если x^2+2x-15=0, то x₁*x₂=-15 - это ответ.

Tatyana Tarasova
There are few people in this country who don’t know
this fantastic woman and great trainer. Tatyana Tarasova
has trained more world and Olympic champions
than anybody else in skating history. Her students
have won about half a hundred gold and a lot of silver
and bronze [brɒnz] medals [ˈmedəlz] at the European
and world competitions. Eleven of her students
have become Olympic champions [ˈʧæmpjənz]. We have
seen them on the podium [ˈpəʊdiəm] crying or laughing
with joy after their victories [ˈvɪktərɪz].
Tatyana is the daughter of Anatoly Tarasov, a famous
ice hockey trainer. For his daughter he has always
been an example of a person who gave all his life to sport. She
began to do figure skating at the age of five but had to end her career
of a skater when she was 18 because of a trauma [ˈtrɔ:mə]. A year later
she started training young athletes. A lot of her students have become
really famous like Irina Rodnina or Alexei Yagudin.
For more than a decade [ˈdekeɪd] Tatyana lived and worked in Connecticut,
USA because in the 1990s there were big problems with stadiums
and sports equipment in Russia. She is sure
that if a sportsman or a sportswoman stops
training, it puts an end to his or her career.
That’s why she did what she could to keep
Russian figure skaters in good form for the
future of Russian national figure skating.
In 2006 Tatyana Tarasova returned to Russia.
Here she started a number of interesting new
projects [ˈprɒʤekts] which have become popular
with the spectators. Tatyana knows everything
about figure skating. Every little detail [ˈdi:teɪl]
