résoudre les équations suivantes 1-( 2x + 3 ) ( x - 4 ) = 0
2- ( 5 - 3x ) ( 4x - 2 ) = 0
3- x ( 5x - 1) ( 3x + 8 ) = 0
4- ( x - 6 ) ( 7x + 4 ) ( 5x - 9 ) = 0
5-3x² = 8
6- 2 x ² + 3 = 0
7- 3 x ² - 14 = 0
8- x (x – 2) = x ² + 16
9- -6 x ²+ 5 = 4 x ² -
10- (x + 2)² = (x + 3)(x - 5)
11- (x - 1)(x + 1) = (x + 2)(x + 3)
12- 8x²- 7x + 11 = -4x ² - 5 + (12x – 3)(x + 2)
qql pourrais m'aider svp !! c pour demain !!! merciii
