Question

Giúp e với ạ 

Answer 1

1) \(2x+2y=2\left(x+y\right)\)

2) \(2x+4y-6z=2\left(x+2y-3z\right)\)

3) \(-4x-8y-12z=-4\left(x+2y+3z\right)\)

4) \(3x-6y-9z=3\left(x-2y-3z\right)\)

5) \(-5x-10xy-15y=-5\left(x+2xy+3y\right)\)

6) \(-7x-14xy-21z=-7\left(x+2xy+3z\right)\)

7) \(6xy-12x-18y=6\left(xy-2x-3y\right)\)

8) \(8xy-24y+16x=8\left(xy-3y+2x\right)\)

Answer 2

9) \(9xy-18x+9=9\left(xy-2x+1\right)\)

10) \(xy-x=x\left(y-1\right)\)

11) \(ax+a=a\left(x+1\right)\)

12) \(mx+my+m=m\left(x+y+1\right)\)

13) \(-ax-ay-a=-a\left(x+y+1\right)\)

14) \(-ax^2-ax-a=-a\left(x^2+x+1\right)\)

15) \(-2ax-4ay=-2a\left(x+2y\right)\)

16) \(2ax+2ay-2a=2a\left(x+y-1\right)\)
