Let P = \(\frac{2x}{x+3}-\frac{x+1}{x-3}+\frac{3-11x}{9-x^2}\). Find the smallest integer x such that P is also an integer.
\(x\ne\pm3\)
\(P=\frac{2x\left(x-3\right)}{\left(x-3\right)\left(x+3\right)}-\frac{\left(x+1\right)\left(x+3\right)}{\left(x-3\right)\left(x+3\right)}+\frac{11x-3}{\left(x-3\right)\left(x+3\right)}\)
\(=\frac{x^2+x-6}{\left(x-3\right)\left(x+3\right)}=\frac{\left(x+3\right)\left(x-2\right)}{\left(x+3\right)\left(x-3\right)}\)
\(=\frac{x-2}{x-3}=1+\frac{1}{x-3}\)
P is an integer if and only if 1 is divisible by \(x-3\)
Therefore \(x-3=\left\{-1;1\right\}\Rightarrow x=\left\{2;4\right\}\)
\(\Rightarrow x_{min}=2\)
The number of the value of x such that x-3/x is the integer number.
Answer: number(s).
Giá trị của x sao cho \(\frac{x-3}{x}\) là số nguyên
Trả lời:.....số
Giải
Để phân số trên nguyên
=>x - 3 chia hết cho x
Vì x chia hết cho x
=> -3 chia hết cho x
=> x thuộc Ư(-3)
=> x thuộc {1; -1; 3; -3}
=> Có 4 giá trị của x
The number of values of x such that \(\frac{\sqrt{x}+1}{\sqrt{x}-3}\) is an integer is
Để \(\frac{\sqrt{x}+1}{\sqrt{x}-3}\in Z\)
=> \(\sqrt{x}\)+ 1 chia hết cho \(\sqrt{x}\)- 3
=> \(\sqrt{x}\)- 3 + 4 chia hết cho \(\sqrt{x}\) - 3
=> 4 chia hết cho \(\sqrt{x}\)- 3
=> \(\sqrt{x}\)- 3 thuộc Ư(4) = {1 ; -1 ; 2 ; -2 ; 4 ; -4}
Ta có bảng sau :
\(\sqrt{x}\)- 3 | 1 | -1 | 2 | -2 | 3 | -3 |
x | 2 | vô tỉ | vô tỉ | 1 | vô tỉ | 0 |
