bonsoir

A = 7 x² + 5 x - 13

B = - 3 x² + 6 x + 3

C = - 12 x² - 2 x + 10

D = 10 x² + 7 x + 1

Bonsoir,

A = 4x² + 3x - 6 + 3x² + 2x - 7

A = 4x² + 3x² + 3x + 2x - 6 - 7

A = 7x² + 5x - 13

B = -5x² + 2x - 9 + 2x² + 4x + 12

B = -5x² + 2x² + 2x + 4x - 9 + 12

B = -3x² + 6x + 3

C = 6x - 2x² + 4 - 10x² - 8x + 6

C = -2x² - 10x² + 6x - 8x + 4 + 6

C = -12x² - 2x + 10

D = 13x² - 3x - 9 - 3x² + 10x + 10

D = 13x² - 3x² - 3x + 10x - 9 + 10

D = 10x² + 7x + 1
