x²-6x+9-(x²+2x+1)=12

x²-6x+9-x²-2x-1=12

-8x=4

x=-1/2

anastejidmitrv: якщо правильніше то х= -0,5
Quilsu: Не имеет значения, -1/2=-0,5.

СРОНО прошу помогите ДАМ 100 БАЛОВ ПЖ!!!!!!!!!!!!!!
1.Reading Rita Nelson is fourteen, and she has changed her school because her parents moved to another town this summer. "Let me tell you about my new school. I'm having a great time. All pupils are very friendly, but it's very different from my old school. First of all school starts at 8.00 here, a whole hour before it did in that school. This morning I forgot about it and got to school ten minutes late, so the teacher put a note into my record-book. I was really angry! There are a lot of other differences in this school, of course. We have seven lessons almost here every day. What else? The school day is different, too. In my former school we finished school at 3.00, and then most pupils went home. Here we finish lessons at 3.30, and then most pupils go to sports practice. Well, they love sports here. I joined gymnastics and football clubs here. A lot of girls play football in this school. I had my first practice yesterday, and I feel tired today. Another important thing here is learning to do practical things. Their metal and wood shops are like small factories, and we are taught to drive as well. It's fantastic. I had my first lesson in a driving tractor yesterday." Choose the right variant.
