Question

factorise ( 1-6z+9z^2)​

Answer 1

Answer:

3z-1 and 3z-1

Step-by-step explanation:

=>1-6z+9z^2

Reordering the sentence

9z²-6z+1

Splitting the middle term

9z²-3z-3z-1

Taking (3z-1) as common,

3z(3z-1)-1(3z-1)

(3z-1)(3z-1)

Therefore, the factors of (1-6z+9z^2) is (3z-1) and (3z-1)
