Answer:
9a^2 +1 - 6a - 6a +2
9a^2 -12a + 3
product = ac= 9a^2 X 3
= 27a^2
sum = -12a
no.s are = -9a , -3a
(9a^2 - 9a)(-3a +3)
9a(a-1) -3(a-1)
(a-1) and (9a - 3)

Answer:
(9a-3) (a-1)
Step-by-step explanation:
(3a-1)^2 -6a+2
= (3a)^2 +2×3a×(-1) + (-1)^2 +6a-2
= 9a^2 -6a + 1 -6a+2
= 9a^2 -12a +3
= 9a^2-9a-3a+3
=9a(a-1) -3(a-1)
= (9a-3) (a-1)
Hope this helps you
