Question

R duire, si possible, les expressions suivantes: A = -g2 - (-9g2) B = T w times 3 C = 8 p times (-5) D = 8c - (-c) E = % times (-y) F = -4 times (-2y) G = 2 w2 - 10 w2 H = - m - 9m I = h - 3h R duire, si possible, les expressions suivantes: A = 9t times 7 B = 2 k2 - 10 k2 C = -8k times (-7 k) D = -10 u times 9 E = 10 c2 - 10 c2 F = -5y - 2y G = 10 times (-8t) H = m2 times 2 I = 6u2 times 5 = 302. R duire, si possible, les expressions suivantes: A = -10 q - 6q B = -q2 times 5 C = -g -(-3g) D = 4 k2 times 7 E = 7 t-(-6) F = 5f times (-8f) G = -8q2 times 3 H = 2 times 6v2 I = -2d times 4

Explanation / Answer

Excercice 9: A = -g^2+9g^2 = 8g^2 B = 21w C = -40p D = 8c +c = 9c E = -5y F = 8y G = -8w^2 H = -10m I = -2h Excercice 10: A = 63t B = -8k^2 C = 56k^2 D = -90u E = 0 F = -7y G = -80t H = 2m^2 I = 30a^2 Exercice 11: A = -16q B = -5q^2 C = -g+3g = 2g D = 28k^2 E = 7t +6 F = -40f^2 G = -24q^2 H = 12v^2 I = -8d
