Answer 1

Step-by-step explanation:

1)(x+3)x + (x+3)y

=>(x+3)(x+y)

2)2(x - a)+ 4m(x - a)

=>(x-a)(2+4m)

=>2(x-a)(1+2m)

3)(x+y)²+(x+y)

=>(x+y)(x+y)+(x+y)

=>(x+y)(x+y+1)

4)a(a+b)-(b+a)

=>a(a+b)-(a+b)

=>(a+b)(a-1)

5)a (x + y + 2) + b(x + y + 2) +C (x+y+2)

=>(x+y+z)(a+b+c)

6)(a + b} -3ab(a + b)

=>(a+b)(1-3ab)

7)a(a - 2c) + b(a - 2c) + (2c-a)

=>(a-2c)(a+b+1)

Answer 2

x+y ,x+3

2x+1,x+y

a-b,a+1
