Bonsoir
Factoriser :
Q = (3x + 2)^2 - x^2
Q = (3x + 2 - x)(3x + 2 + x)
Q = (2x + 2)(4x + 2)
Q = 2(x + 1) * 2(2x + 1)
Q = 4(x + 1)(2x + 1)
R = t^2 - 22t + 121
R = t^2 - 2 * t * 11 + 11^2
R = (t - 11)^2
S = (8x + 5)^2 - (x + 1)^2
S = (8x + 5 - x - 1)(8x + 5 + x + 1)
S = (7x + 4)(9x + 6)
S = (7x + 4) * 3(3x + 2)
S = 3(7x + 4)(3x + 2)
T = 4u^2 + 400u + 10000
T = (2u)^2 + 2 * 2u * 100 + 100^2
T = (2u + 100)^2
U = x^2 - 3x + 9/4
U = x^2 - 2 * x * 3/2 + (3/2)^2
U = (x - 3/2)^2
V = v^2 + 26v + 169
V = v^2 + 2 * v * 13 + 13^2
V = (v + 13)^2
W = (x + 16)^2 - (8x + 1)^2
W = (x + 16 - 8x - 1)(x + 16 + 8x + 1)
W = (-7x + 15)(9x + 17)
X = 4/9 t^2 + 4/3 t + 1
X = (2/3 t)^2 + 2 * 2/3 t * 1 + 1^2
X = (2/3 t + 1)^2
