Question

How do you factor `-2x^3 + 16x`?

Answer 1

`-2x(x^2-8)` or `-2x(x-sqrt(8))(x+sqrt(8))`

Explanation:

First take out the -2, so it'll become `-2(x^3-8x)`

Then notice that you can take out an x from both terms, so it'll simplify to `-2x(x^2-8)`.

This can be further simplified down to `-2x(x-sqrt(8))(x+sqrt(8))`
