pouvez vous developper ces expressions svp:
A = 12x² + (4x + 5)²
B = 7x – (6x + 2)²
C = -16x² - (4x + 1)(4x – 1)

Bonjour

Developper :

A = 12x² + (4x + 5)²

A = 12x^2 + 16x^2 + 40x + 25

A = 28x^2 + 40x + 25

B = 7x – (6x + 2)²

B = 7x - (36x^2 + 24x + 4)

B = 7x - 36x^2 - 24x - 4

B = -36x^2 - 17x - 4

C = -16x² - (4x + 1)(4x – 1)

C = -16x^2 - (16x^2 - 1)

C = -16x^2 - 16x^2 + 1

C = -32x^2 + 1
