1) \(5\left(x-y\right)-y\left(x-y\right)\)
\(=\left(x-y\right)\left(5-y\right)\)
2) \(x\left(y+1\right)+8\left(y+1\right)\)
\(=\left(y+1\right)\left(x+8\right)\)
3) \(5\left(x-y\right)-x\left(x-y\right)\)
\(=\left(x-y\right)\left(5-x\right)\)
4) \(z\left(x+y\right)-5\left(x+y\right)\)
\(=\left(x+y\right)\left(z-5\right)\)
5) \(3x\left(x+5\right)-2\left(5+x\right)\)
\(=3x\left(x+5\right)-2\left(x+5\right)\)
\(=\left(x+5\right)\left(3x-2\right)\)
6) \(x^2\left(x-1\right)+4\left(x-1\right)\)
\(=\left(x-1\right)\left(x^2+4\right)\)
