How do you simplify `ab(b^2-0.4a^2b)`?

Answer 1

See the entire simplification process below:

Explanation:

To simplify this expression multiply each term within parenthesis by `color(red)(ab)`:

`color(red)(ab)(b^2 - 0.4a^2b) = (color(red)(ab) xx b^2) - (color(red)(ab) xx 0.4a^2b) =`

`ab^3 - 0.4a^3b^2`
