Question

e)3a-3b+ax-bx f)7ax-7a+bx-b g)ax-2x+yx-y h)ax+a+bx+b

Answer 1

E)3a-3b+ax-bx

3a - 3b + ax - bx =
3(a - b) + x(a - b)
(a - b)(3 + b)   resposta

 f)7ax-7a+bx-b

7ax - 7a + bx - b =
7a(x - 1) + b(x - 1)
(x - 1) (7a + b) resposta

 g)ax-2x+yx-y

ax - 2x + y - y ????????

h)ax+a+bx+b

ax + a + bx + b =
a(a + 1) + b(x + 1) =
(a + 1) (a + b)  resposta  

Answer 2

E)3a-3b+ax-bx ==> 3a + ax - 3b - bx ==> a(3 + x) - b(3 + x) ==> (3 + x)(a- b)
 
f)7ax-7a+bx-b ==> 7ax - 7a + bx - b ==>7a(x - 1) + b(x - 1) ==> (7a + b)(x- 1)

g)ax-2x+yx-y ==> ax -2x + yx - y ==> x(a - 2) + y(x - 1)

h)ax+a+bx+b ==> ax + a + bx + b ==>a(x + 1) + b(x + 1) ==> (a + b)(x + 1)
