(a+b)x+(a+b)y

(5-x)a=(5-x)b

(2a+b)y-6(2a+b)

(4z+3)x-(4z+3)

x²(10a-1)y+(1-2x)-z(1-2x)

(7b-5a)(x+y)+(x+y)(7b-5a)

Answer 1

1. xa + xb + ya +yb

2. 5a - ax = 5b - bx

3. 2ay + by - 12a +65

4. 4xz + 3x - 4xz - 3x

5.

6. 7bx -5ay + 7bx -5ay

Answer 2

a) (a+b)x + (a+b)y = (a+b)(x+y)

b) (5-x)a = (5-x)b 

(5-x)(a-b)=0

c) (2a+b)y - 6(2a+b) = (2a+b)(y-6)

d) (4z+3)x - (4z+3) = (4z+3)(x-1)

e) x² (10a-1)y + (1-2x)-z(1-2x) = x² (10a-1)y + (1-2x)(1-z)

f) (7b-5a)(x+y)+(x+y)(7b-5a) = (7b-5a) ((x+y)+(x+y))
