Complete this review of a digital camera by typing in the superlative form of the adjectives in brackets With 60 megapixels and optical zoom, the 0930 is (1) (good) the high resolution digital camera available in this price range. You can use the 0930 to produce some of (2) (sharp) the images possible and take detailed photos for printing up to poster size. In addition, it has a 3x optical and 5x digital zoom, giving 15x total zoom when combined (3) (high) the in many digital camera under £50. ASR technology prevents the degradation of image clarity and colour common in flash photography. With ASR, the effects of camera shake are reduced in lower light conditions, you can even take well exposed sharper pictures in low light without using a flash at all. It guarantees (4)) (bright) the and (5) (natural) the pictures possible at his price.

получается делаем так:

сначала решаем уравнение как и обычно т.е. теоремой виетта или дискриминантом

х^2-4х+3=0

я решу теоремой виетта:

сумма корней равна 4

произведение 3

значит корни 1 и 3

далее:

есть такая формула разложение на множетели квадратного уравнения выглядит так:                 a(x-x1)(x-x2), где а-множетель перед квадратом в нашем случае это 1, х1 и х2 - корни. 

подставим в неё наши корни, получим  (x-1)(x-3)=0

так а теперь решим это неравенство  (x-1)(x-3)> 0

методом интегралов ( тут 3 промежутка от минус бесконечности до 1 от 1 до 3 и от 3 до плюс бесконечности):

допустим х =0, подставим (0-1)(0-3)=3 знак + значит в промежутке от минус бесконечности до 1 знак + 

от 1 до 3 знак -

от 3 до плюс бесконечности +

ответ: х принадлежит промежутку  от минус бесконечности до 1 и  от 3 до плюс бесконечности

1.The weather was not good.The sky was full of dark clouds and soon it started raining heavily.
2.While he was driving to the airport, the storm got worse. Suddenly, a huge flash of lightning struck a tree. It came crashing down just metres in front of his car. The fallen tree completely blocked the road, so he was stuck. He tried to call the emergency services on his mobile, but the line was dead.
3.He was positive that he would miss his plane, so he turned on the radio and tried to get used to the idea.
4. There was a loud knock at the window, it was a young man in leather clothes. The yound man grabbed his bags, climbed carefully onto the motorcycle and shouted urgently, “To the airport, please!”
It was his first time on a motorcycle so he was terrified. The young man drove so fast that autor kept my eyes tightly shut all the way. “We are here!” he said.He looked at my watch and saw that I was just in time for my flight.
5.As soon as his plane took off, he breathed a huge sigh of relief. He could now relax and enjoy his holiday.
