Bonjour pouvais vous m'aider svpppp Développe et réduis les expressions : G = 3x - 5 + 5(2x - 2) H = 4y - 6(3 - 2y) + 4(y - 1) I = 5t2 + 3(2t - 3) - 2t(t - 5)​

Bonjour,

G = 3x - 5 + 5(2x - 2)

3x-5+10x -10=

13x -15

H = 4y - 6(3 - 2y) + 4(y - 1)

4y -18 +12y +4y -4=

20y -22

I = 5t2 + 3(2t - 3) - 2t(t - 5)​

5t² +6t -9 -2t² +10=

3t² +6t +1

Salut

G = 3x - 5 + 5(2x - 2)

G = 3x - 5 + 10x - 10

G = 13x - 15

H = 4y - 6(3 - 2y) + 4(y - 1)

H = 4y - 18 + 12y + 4y - 4

H = 20y - 22

I = 5t² + 3(2t - 3) - 2t(t - 5)

I = 5t² + 6t - 9 - 2t² + 10t

I = 3t² + 6t - 9
