Sagot :
c = 3 * (-4) / (-1) *2 = -12/-2 = 6
F = (-3)² + 2(-3)*(-2) + (-2)² = 9 + 2*6 + 4 = 25
F = (-3)² + 2(-3)*(-2) + (-2)² = 9 + 2*6 + 4 = 25
Bonsoir
C = (6 -3) x (-9 +5) / (7 -9 +1) x2
C = 3 x -4/-1x 2
C = -12 / -2 = 6
F = x² +2xy + y²
F = (-3)² + 2 (-3* -2) + (-2)²
F = 9 + ( 2 * 6) +4
F = 9 + 12 + 4 = 25
C = (6 -3) x (-9 +5) / (7 -9 +1) x2
C = 3 x -4/-1x 2
C = -12 / -2 = 6
F = x² +2xy + y²
F = (-3)² + 2 (-3* -2) + (-2)²
F = 9 + ( 2 * 6) +4
F = 9 + 12 + 4 = 25
