Question

How do you find the product `2pr^2(2pr+5p^2r-15p)`?

Answer 1

`color(brown)(=> 4 p^2 r^3 + 10 p^3 r^3 - 30 p^2 r^2`

Explanation:

`2 pr^2 ( 2pr + 5p^2r - 15p)`

`=> 2pr^2 * 2pr + 2pr^2 * 5p^2r - 2pr^2 * 15p, " removing the bracket"`

`color(brown)(=> 4 p^2 r^3 + 10 p^3 r^3 - 30 p^2 r^2`
