Bonsoir,
A1 = -7+2 = -5
A2 = 14/(-7) = -2
B1 = (7-(-5)/(-2)² =(12)/(4) = 3
B2 = (4x(-6)-1) +5 = (-24-1)+5 = -25+5 = -20
C1 = -2 + (-4) x (-3) - (-2) x (-2) = -2+12 - (+4) = -2+12-4 = 6
C2 = (-7+(-1)x(-4))/(-12-(-3+3x(-2)) = (-7+4)/(-12-(-3-6)) = -3/(-12-(-9) = -3/-3 = 1
D1 = -2+7x(-4)+5x(-5) = -2-28-25 = -55
D2 = 200 + ((-6)²+(-8)²))x-1 = 200+(36+64)x-1 = 200+(+100)x-1
= 200-100 = 100
Bonne soirée
