Question

How do you factor `x^3+8x^2-20x`?

Answer 1

`x(x+10)(x-2)`

Explanation:

First, you would divide `x` out of the whole expression to get
`x(x^2+8x-20)`
You would then factor `x^2+8x-20`. To factor it, you need to find two numbers that added together equal `8` and multiplied together equal `-20`. These two numbers would be `10` and `-2`, giving us
`x(x+10)(x-2)`
