Step-by-step explanation:
Answer:
(7x^2 -1)(x - 2).
Step-by-step explanation:
7x^3 - 14x^2 - x + 2
We can factor this by grouping - that is factoring the first 2 terms and the last 2:
= 7x^2(x - 2) - 1(x - 2) <-- the x - 2 is common to both parts so we have:
(7x^2 -1)(x - 2).
It goes in the order 3,1,2,4
