a: \(A=\dfrac{x}{x+3}-1=\dfrac{x-x-3}{x+3}=\dfrac{-3}{x+3}\)
\(B=\dfrac{9-x^2+x^2-9-x^2+4x-4}{\left(x+3\right)\left(x-2\right)}=\dfrac{-\left(x-2\right)^2}{\left(x-2\right)\left(x+3\right)}=\dfrac{-x+2}{x+3}\)
b: B nguyên
=>-x-3+5 chia hết cho x+3
=>x+3 thuộc {1;-1;5;-5}
=>x thuộc {-2;-4;-8}
c: P=A:B
=(-3/x+3):(-x+2)/(x+3)
=3/(x-2)
