Question

factorise 1+a+7x+7ax​

Answer 1

Answer:

(i) (x + y) (x + 9)  

(ii) (2y - 3) (3x - 2)  

(iii) (2a + 1) (5b + 3)    

(iv) (x2 + 1) (x + 1)

(v) (a - 1) (a + y)

(vi) (x - y) (x2 + 5)

(vii) (a + 3) (a - 1)

(viii) (x + y) (3a - 2b)

(ix) (x + y) (x – z)

(x) a(a - 1) (a – b2)

Answer 2

Answer:

1+7x + a + 7ax

1(1+7x) + a(1+7x)

now we have two solutions

(1+a) (1+7x)

a= -1

and x= -1/7
