Question

How do you multiply `4x^2y(-x^2-x+10)`?

Answer 1

`-4x^4y-4x^3y+40x^2y`

Explanation:

Multiply each term in the bracket by `4x^2y`

`rArrcolor(red)(4x^2y)(-x^2-x+10)`

`=(color(red)(4x^2y)xx-x^2)+(color(red)(4x^2y)xx-x)+(color(red)(4x^2yxx10))`

`=-4x^4y+(-4x^3y)+40x^2y`

`=-4x^4y-4x^3y+40x^2y`
