3 (8p^2-5p)-5(3p^2-2p+4)?

24p² - 15p - 15p² + 10p - 20
9p² - 5p - 20

= 3(8p² - 5p) - 5(3p² - 2p + 4)
= 24p² - 15p - 15p² + 10p - 20
= 9p² - 5p - 20

Answer: 9p² - 5p - 20

3(8p^2-5p) - 5(3p^2-2p+4)
24p^2-15p - 15p^2+10p-20
9p^2-5p-20

3(8p² - 5p) - 5(3p² - 2p + 4)

= 24p² - 15p - 15p² + 10p - 20

= 9p² - 5p - 20

answer: 9p^2 - 5p - 20


solution:

use distributive property:

24p^2 - 15p -15p^2 + 10p -20

combine like terms:

9p^2 - 5p - 20

3(8p^2 - 5p) - 5(3p^2 - 2p + 4)
= 3*8p^2 - 3*5p - 5*3p^2 + 5*2p - 5*4
= 24p^2 - 15p - 15p^2 + 10p - 20
= 24p^2 - 15p^2 - 15p + 10p - 20
= 9p^2 - 5p - 20
