Question

How do you factor completely `16x^3-10x^2-8x`?

Answer 1

`2x(8x^2-5x-4)`

Explanation:

Since this expression has no constant, you can factor out `2x`:

`16x^3 -10x^2 -8x`

`=2x(8x^2-5x-4)`

And in this case, you can't factor the quadratic any further, so the cubic expression is as factored as possible.
