Answer 1

2:

1: =2y(x+2)-3(x+2)

=(x+2)*(2y-3)

2: =3(x+4)-x(x+4)

=(x+4)(3-x)

3: =2(x+5)-x(x+5)

=(x+5)(2-x)

4: =x(x+6)-3(x+6)

=(x+6)(x-3)

5: =x(x+y)-5(x+y)

=(x+y)(x-5)

6: =x(x-y)+2(x-y)

=(x-y)(x+2)

7: =2x(x-5)+3(x-5)

=(x-5)(2x+3)

8: =x(x+y)+a(x+y)

=(x+y)(x+a)

9: =a(x+y)-4(x+y)

=(x+y)(a-4)

10: =a(x-y)+b(x-y)

=(x-y)(a+b)

11: =z(x+y)-5(x+y)

=(x+y)(z-5)

12: =5(x-y)+a(x-y)

=(x-y)(a+5)
