Sa me reste le b. et le d qui peut m aide svp

b =5(x-1)(x+1) =3(x-1)(x+2)
5(x-1)(x+1)-3(x-1)(x+2) =0
(x-1)(5x+5-3x-6) =0
(x-1)(2x-1) =0

x-1 = 0                2x-1 =0
x = 1                      x = 1/2

d = 3² -(3x-1)² =0
(3-3x+1)(3+3x-1) =0
(-3x+4)(3x+2) =0

-3x+4 =0                      3x+2 =0
-3x = -4                            x = -2/3
x = -4/-3 = 4/3
