Developper et reduire E. 4(2y-3) -3 (5-6y) F.(5y+6) + (4y-2) G. (2y-5) - (5y+3) I. (-4x +6) (2x-3) Mersi d'avance..!

E = 4(2y - 3) - 3(5 - 6y)
= 8y - 12 - 15 + 18y
= 26y - 27

F = (5y + 6) + (4y - 2)
= 9y + 4

G = (2y - 5) - (5y + 3)
= 2y - 5 - 5y - 3
= -3y - 8

I = (-4x + 6)(2x - 3)
= -8x² + 12x + 12x - 18
= -8x² + 24x - 18
