A = 3,5x ? 4,2x + 2,1x C = 4x ? 4y + 8 E = 3t + 9u + 3. B = 4t ? 5tx + 3t D = x2 + 3x
? 5x2 F = 3x ... 4x ? 4y + 4x2 E = 3t + 3x3u + 3x1. = x(3,5 ? 4,2 + 2,1) = 4(x ? y + 2)
= 3(t + 3u + 1). = 1,4x. B = 4t ? 5tx + 3t D = x x x + 3x - 5x x x F = 3x ? 1x. = t(4 ? 5x
+ 3) = x(x + 3 ? 5x) = x( 3 ? 1 ). = t(7 ? 5x) = x(-4x + 3) = 2x. Exercices conseillés ...
