Question

How do you factor `14x^2y^3+5xy^3-9y^3`?

Answer 1

`y^3(14x^2+5x-9)`

Here's how I did it:

Explanation:

To factorize something, you have to find everything that all the expressions have in common. That means we need to find the GCF (Greatest Common Factor) of all expressions.

`14x^2y^3+5xy^3-9y^3`

We can see that they all have `y^3`, meaning we can factor that out.

If we factor out `y^3`, what we have left over is:
`14x^2+5x-9`

So finally we write it like this:
`y^3(14x^2+5x-9)`

Hope this helps!
