Bonjour,aidez moi pour reduire des expressions (j'ai rien compris meme avec de l'aide !!!! ).C'est : B=x-(11-x²)+(12*-3) D=3t+(2t²+9)-(-9t+t²) E=-5(-2s+7)-9(3-11s) F=-10(4-3x)+(3x+1)*6 et G=6(5t+3)-8(-3+6t) PLEASE HELP ME !!!!!!!!

Sagot :

B = x-(11-x²)+(12*(-3))
B = x-11+x²-36
B = x²+x-47

D = 3t+(2t²+9)-(-9t+t²)
D = 3t+2t²+9+9t-t²
D = t²+12t+9

E = -5(-2s+7)-9(3-11s)
E = 10s-35-27+99s
E = 109s-62

F = -10(4-3x)+(3x+1)*6 
F = -40+30x+18x+6
F = 48x-34

G = 6(5t+3)-8(-3+6t) 
G = 30t+18+24-48t
G = -18t+42
