Câu 6:
The number of values of such that
is an integer is
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

1 How many triples of integers (a,b,c) are there such that
?
2
ABC and RTS are similar triangles.
The value of x is 3 The sum of 2 positive integer numbers is greater than their product if the smaller number is
2) Vì ABC và RTS là 2 tam giác đồng dạng nên:
\(\frac{AB}{RT}=\frac{BC}{TS}\Leftrightarrow\left(\frac{8}{4}\right)=\frac{x}{5}\Rightarrow x=10\)

1.If 2x-y=5 then the value of M=\(\left(x+2y-3\right)^2-\left(6x+2y\right)\left(x+2y-3\right)+9x^2+6xy\)
\(+y^2\)
2.The free coefficient in the following poly nomaial: \(\left(2x-2\right)\left(x+1\right)\left(7-x^2\right)is:\)
3.The greatest integer number x such that \(\frac{2x-1}{x-3}-1< 0\) is:
4.How many of the integer n such that satisfy the inequality \(\left(n-3\right)^2-\left(n-4\right)\left(n+4\right)< =43\) are less than 3?
5.The opposite fraction of \(\frac{x-2}{7-x}\) is:
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 \(x-3=\left\{-1;1\right\}\Rightarrow x=\left\{2;4\right\}\)
\(\Rightarrow x_{min}=2\)
