Question

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

Answer 1

Answer: 25 is the asnwer

Step-by-step explanation:

Answer 2

Solution is p(5p-4m+25n)

Step-by-step explanation:

Given:

3p(p-4m+5n) = $3p\times p-3p\times4m+3p\times5n$

                     = $3p^2 -12pm+15pn$  

4p(10n-4m+2p) = $4p\times 10n-4p\times 4m+4p\times2p$

                         = $40pn- 16pm+8p^2$

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

⇒4p(10n-4m+2p)-3p(p-4m+5n)               [given]

⇒$40pn- 16pm+8p^2 - [3p^2 -12pm+15pn]$

⇒$40pn- 16pm+8p^2 - 3p^2 +12pm-15pn$

⇒$5p^2-4pm+25pn$

⇒p(5p-4m+25n)
