Question

3n^2(u-2)-5(u-2) =[ ] find the complete factored

Answer 1

\(3n^2(u-2)-5(u-2)\)

There is a common factor of \(u-2)\) that you can factor out. Let's look at a similar by different question: if you had:
\(3n^2\color{blue}{y}-5\color{blue}{y}\), how would you factor that

Answer 2

If this is what you mean:
\( \color{blue}{y}(3n^2-5)\)

Answer 3

Then you can just use the same method of factoring by just replace \(y\) with \(u-2\)
