Kalau gak salah Y ._. :
(2y (3y +5)) x (4y (2y -8) = (6y² +10y) x (8y² -32y)
 = 6y² (8y² -32y) +10y (8y² -32y) 
 = 48y⁴ -192y³ +80y³ -320y²
 = 48y⁴ -112y³ -320y²
emm.. makasihh yahh ?? itu ge kalo bener kalo salah mah gpp lah
Iya :)

((2y x 3y)+(2y x 5)) ((4y x 2y)(4y x -8))
(6 y^{2} + 10y) (8 y^{2} - 32y
6 y^{2} + 8y y^{2} + 10y - 32y
14 y^{2} - 22y
