Answer 3

Bài 1:

a: \(=3xy\left(z+2\right)\)

b: \(=\left(x-3\right)\left(2+x\right)\)

c: \(=4\left(x^2-2xy+y^2-4\right)\)

\(=4\left(x-y-2\right)\left(x-y+2\right)\)

d: \(=5x\left(x+y\right)-\left(x+y\right)=\left(x+y\right)\left(5x-1\right)\)

e: \(=5\left(x^2-2xy+y^2-4z^2\right)\)

\(=5\left(x-y-2z\right)\left(x-y+2z\right)\)

f: \(=\left(x+y\right)^3\)
