Нужно возвести во вторую степень корни:

(9х + 49) - (х^2 + 1) = 2

9х + 49 - х^2 - 1 - 2 = 0

х^2 + 9х + 45 = 0

Потом решаем через дискриминант. Все формулы есть в интернете. :)

vladddddd11: дорешай

iramekhonoshina00: Могу добавить: а = 1; в = 9; с = 45

iramekhonoshina00: Ладно

vladddddd11: спасибо

iramekhonoshina00: D = 9^2 - 4 x 1 x 45

vladddddd11: дорешай пж

vladddddd11: спасибо

iramekhonoshina00: 49 - 180 = -131

iramekhonoshina00: дискриминант отрицательный - решений нет

Помогите пожалуйста

Megan. My dad works in a local factory, and once he told me about an idea their management had. They decided to get involved in environmental protection. They spent a huge amount of money on special filters for water and air. I think every company should be that responsible to keep the planet safe.

Amy. I'm against government politics, when they use armies to get what they want. Neither territories, nor natural resources or anything else in the world can justify people's deaths.

Billy. When I did my science project, I learnt about Pompeii. And it shocked me. I read about the bodies of people and animals, found under a thick layer of ash. And then I realised that
nowadays these things are possible too. Have you heard about Yellowstone in the USA?

Lucy. I am convinced that nowadays people have more health problems because of this issue. We need to stop using cars that much, reduce burning coal, gas, and oil. Besides, giant producers have to bear responsibility for using some kinds of chemicals, which are able to ruin
the atmosphere.

Molly. Once I went to the zoo and saw the falcon. It was so beautiful and interesting to watch. How frustrated I was when a man in the zoo told me that there are plenty of birds in danger. But he also told me that each of us has an opportunity to help with a small donation to the fund! So now I'm saving up for a great purpose.

Charlie. My family supports the idea that we shouldn't throw out good food. It's not OK
because there are a lot of people in the world, who are less lucky than we are and suffer from not having enough to eat.
