Réduire, si possible, les expressions suivantes.
G= -5x x (- 8x) H=-2 * (- 4x2)
1 = 8 X (- 6x) J = 5x2 x (-4)
K=- 7x X3 (- 4x) L = 7x * 3 * (- 10x)

Réponse:

[tex]g = - 5x \times ( - 8x) = 40 {x}^{2} \\ h = - 2 \times ( - 4 \times 2) = - 2 \times ( - 8) = 16 \\i =8 \times ( - 6x) = - 48x \\j = 5 \times 2 \times ( - 4) = - 40 \\k = - 7x \times 3( - 4x) = - 7x \times - 12x = 84 {x}^{2} \\l = 7x \times 3 \times ( - 10x) =21x \times ( - 10x) = - 210 {x}^{2} [/tex]
