Answer 2

SOLUTION

TO DETERMINE

Subtract 3p(p - 4m+5n) from 4p(10n - 3m+2p)

EVALUATION

Here we have to Subtract

3p(p - 4m+5n) from 4p(10n - 3m+2p)

Here

3p(p - 4m+5n)

= 3p² - 12mp + 15np

Again

4p(10n - 3m+2p)

= 40np - 12mp + 8p²

Hence the required result

= 4p(10n - 3m+2p) - 3p(p - 4m+5n)

= ( 40np - 12mp + 8p² ) - ( 3p² - 12mp + 15np )

= 40np - 12mp + 8p² - 3p² + 12mp - 15np

= 5p² + 25np
