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
