BonjourE = 10x² - 16x + 15x - 24 - (10x² - 2x - 20x + 4)E = 10x² - 16x + 15x - 24 - 10x² + 2x + 20x - 4E = 10x² - 10x² - 16x + 15x + 2x + 20x - 24 - 4E = 21x - 28F = 25x² - 40x - 10x + 16 - (3x² + 21x - 5x - 35)F = 25x² - 40x - 10x + 16 - 3x² - 21x + 5x + 35F = 25x² - 3x² - 40x - 10x - 21x + 5x + 16 + 35F = 22x² - 66x + 51G = 2 (3x - 2x² + 21 - 14x) + 20x² + 5x - 8x - 2G = 6x - 4x² + 42 - 28x + 20x² + 5x - 8x - 2G = - 4x² + 20x² + 6x + 5x - 8x - 28x + 42 - 2G = 16x² - 25x + 40.

Bonjour,Développer puis réduire :E = 10x²-16x+15x-24-(2x-4)(5x-1)E = 10x²-16x+15x-24-(10x²-2x-20x+4)E = 10x²-16x+15x-24-(10x²-22x+4)E = 10x²-16x+15x-24-10x²+22x-4E = -16x+15x-24+22x-4E = 21x-24-8E =21x-28F = 25x²-40x-10x+16-(3x-5)(x+7)F = 25x²-40x-10x+16-(3x²+21x-5x-35)F = 25x²-40x-10x+16-(3x²+16x-35)F = 25x²-40x-10x+16-3x²-16x+35F = 22x²-40x-10x+16-16x+35F = 22x²-66x+16+35F = 22x² - 66x + 51G = 2(x+7)(3-2x)+(5x-2)(4x+1)G = (2x+14)(3-2x)+(5x-2)(4x+1)G = (2x+14)(3-2x)+20x²+5x-8x-2G = 6x-4x²+42-28x+20x²+5x-8x-2G = -25x-4x²+42+20x²-2G = -25x+16x²+42-2G = -25x+16x²+40G = 16x²-25x+40Bonne soirée.
