Question

E) (3p-4)2 expoente -3p. (2p+2)+(p-7)2 expoente D)(2/5y+1/2)2 expoente -1/5y-3/25y2expoente alguém pra me ajudar

Answer 1

E)
(3p - 4)² - 3p * (2p + 2) + (p - 7)² =
(9p² - 24p + 16) - (6p² + 6p) + (p² - 14p + 49) =
9p² - 6p² + p² - 24p - 6p - 14p + 16 + 49 =
4p² - 44p + 65

D)
(2y/5 + 1/2)² - 1y/5 - 3y²/25
(4y²/25 + 2y/5 + 1/4) - 1y/5 - 3y²/25 =
4y²/25 - 3y²/25 + 2y/5 - 1y/5 + 1/4 =
y²/25 + y/5 + 1/4 =
(y/5 + 1/2)²
