plss help me to answer those problems in algebra.

G. Perform each indicated division. 1) (12x3y2 - 24x2y3 + 40x5y5) = 4x2y2 2) (9m3n2 - 3m2n3 + 2mn+) : 6man 3) (2x2 - x - 15) + (2x + 5) 4) (4x3 - 7xy2 + 3y3) + (2x + 3y) 5) (12a3 - 11a2 - 12a - 25) + (3a -5) H. Use synthetic division to determine the quotients. 1) (x3 - 3x2 + 7x + 5) + (x -2) 2) (5x3 - 4x + 12) + (x+ 2) 3) (12 + 2x2 - 3x4) + (x+1) 4 ) (x 4 _ + x2 3 + 4 F + (x - 1) 5) (3 + 2x - 6x3 - 4x4) + (2x + 3)
