a)x2 +x =0

x(x+1)=0

* x=0

* x+1=0

      x=0-1

      x=-1

Vậy x=0 hoặc x=-1

2.(x-1) +3(x-2) =x-4

        2x-2+3x-6=x-4

             x+3x-x=-4+2+6

                    3x=4

                     x=\(\frac{4}{3}\)

a, 

x2 +x =0

\(\orbr{\begin{cases}x^2=0\\x=0\end{cases}}\)

Vậy x= 0

b,2.(x-1) +3(x-2) =x-4

2x - 2 + 3x - 6 = x - 4 

2x + 3x - x = -4 +6 + 2

4x                = 0

Vậy x = 0

WHO WANTS TO BE A MILLIONAIRE?

One of the most popular quiz programmes on television in the world is called Who Wants To Be A Millionaire? In Britain, the quiz master is Chris Tarrant. He asks the contestants fifteen questions. The first questions are easy but later they are more difficult. If you can answer the fourteenth question, you can win £500,000. You can win a million pounds if you can answer the last question. Of course, the last question is very difficult.

All the questions on Who Wants To Be A Millionaire? are multiple-choice questions. After you hear the question, you see four answers. Only one answer is correct. You have to choose the correct answer. If you don't know the answer to a question, there are three ways you can get help: you can ask the quizmaster to take away two wrong answers: you can ask the studio audience which answer is right; or you can telephone a friend and ask for help. You can only do these things once. Very few people win the million pounds. The first person won a millon pounds one year after the programme started.
