Question

Factor the polynomial by grouping: 3n^3-3n^2+n-1

Answer 1

@Luis_Rivera mind helping me in this problem?

Answer 2

From first two terms if you factor out 3n that what will you get??

Answer 3

I mean from this:

\[3n^3 - 3n^2\]

Take \(3n^2\) common from both..

Answer 4

n^2

Answer 5

Take common from both..

See here:

\[\large 3n^3 - 3n^2 + (n-1) \implies 3n^2(n - 1) + 1(n-1)\]
\[\large \implies (3n^2+1)(n-1)\]
