4. Read the text and do the tasks
Almost a hundred thousand people were killed and half a million homes destroyed as a result of an earthquake in Tokyo in 1923. The earthquake began a minute before noon when the habitants of Tokyo were cooking their midday meals. Thousand of stoves were overturned as soon as the earth began to shake. As a result, small fires broke out everywhere and quickly spread. The fire engines were prevented from going to help because many of the roads had cracked open. It was impossible to use fire fighting equipment as most of the water pipes had burst. Consequently, over ninety percent of the damage was caused by fire rather than by the collapse of buildings
These sentences are T (true) or F (false)
1. A hundred thousand people were killed in Tokyo in 1923 because of an earthquake
2. The earthquake began a minute before midnight
3. The fire engines were prevented from going to help because most of the water pipes had burst
4. Over ninety percent of the damage was caused by fire
N(x) = 2x + x3 + x2 - 4x - x3
= x2 - 2x
N(x) = 0 <=> x2 - 2x = 0
<=> x(x - 2) = 0
<=> x = 0 hoặc x - 2 = 0
<=> x = 0 hoặc x = 2
Vậy nghiệm của N(x) là 0 và 2
\(N\left(x\right)=2x+x^3+x^2-4x-x^3=x^2-2x=x\left(x-2\right)\)
Để N(x) có nghiệm => x(x-2)=0
\(\Leftrightarrow\orbr{\begin{cases}x=0\\x-2=0\end{cases}\Leftrightarrow\orbr{\begin{cases}x=0\\x=2\end{cases}}}\)
Vậy x=0; x=2
