greetings from rome! i'm visiting italy with mark, my friend (1)
dad works in rome. his house is in an area (2)
all the best
places to visit are, and that's (3) _
it's the perfect area for us
stay at. yesterday we visited the colosseum; that's the place
_ gladiators used to fight. tomorrow mark's showing me
places from that film we watched together. i can't remember what
it's called, but tom hanks is the actor (5)
stars in it. the
picture on the postcard is the pantheon. it's the temple,
we visited today. hey, what's the italian team
you like? is it lazio or roma? anyway, we're watching
them play each other tomorrow night!
see you soon,
lee

(a-b)^2=a^2-2ab+b^2
получаем (x^2-4x+4)/(x-1)<0
решаем квадратное уравнение
x^2-4x+4=0
D=0, значит -b/2a и один корень
x=2
:> a(x-x1)(x-x1)(x-2)(x-2)
это у нас такая формула есть (не знаю как она называется)
значит общая у нас будет (x-2)(x-2)/(x-1)<0
у нас неравенство, значит x=2 x=1
пишем это на линию
___+1-2+>
считаем интервалы + и -
нам нужно меньше нуля , значит от 1 до 2
ответ : "(1;2)"
(скобки не квадратные потому что у нас не меньше либо равно 0, а просто меньше нуля)
