Bonjour, j’arrive pas à faire le devoir de maths si vous pouvez m’aider ça serait cool 2) Factoriser:
Factoriser si possible les expressions suivantes :
a(x) = 9x2 - 6x + 1
b(x) = 121x? - 89
C(x) = 25x? - 30x + 9
d(x) = (x - 3)(2x + 1) + 2(x - 3)
e(x) = (3x + 7)2 – (3x + 7)(2x - 1)
f(x) = (5x - 1)(4x + 9)2 + 3(2x - 10)(4x + 9)
9(x) = (8x - 16)(3x - 1) + (x - 2)(3x + 1)
h(x) = 9x” – 25 + (3x - 5)(2x + 1)
i(x) = 16x? + 8x + 1 + (4x + 1) (9x - 24)
j(x) = 2(9x - 3)2 - (3x - 1)(2x + 7)
k(x) = (21x - 7)(3x - 1) - (6x - 2)(9x - 3)
