Вычисляем через дискриминант. D=13^2-4*8*(-62)= 2153.

D>

x1,2= -b+-√D/2

x1= -13+√2153/16

x2= -13-√2153/16

/ - знак дроби, то есть числа после этого знака будут знаменателем.

ОЧЕНЬ СРОЧНО! ПОМОГИТЕ С ПЕРЕВОДОМ!

Dear Polly,
How are the things going? I am as busy as a bee these days. Lots of homework, you know... But a little exercise each day helps me keep fit. I'm usually very tired after sitting at the desk for hours. I go jogging in the park every morning. Today after half an hour run I feel fine.
Dan has joined the school Sports Club this year. He wants to set a school record in swimming and running, and he is training hard for that. Everyday training has done wonders for his stamina. Dan's parents want him to participated in sports competitions. They are really proud of his wonderful achievements.
Now we've got a new PEbteacher at school. He's going to start a badminton club, which sounds like fun. So, I think I'll try that - though I hardly imagine where I'll find the time.
What sports do you do, Polly? Would you like to join any sports club?
Write to me soon.
Best wishes,
Ann
