Bonsoir
Factoriser :
G = 18x^2 - 45
G = 9 * 2x^2 - 9 * 5
G = 9(2x^2 - 5)
H = 28x^2 + 35x
H = 7x * 4x + 7x * 5
H = 7x(4x + 5)
I = 20ab + 4ac
I = 4a * 5b + 4a * c
I = 4a(5b + c)
J = 24xyz - 30xy
J = 6xy * 4z - 6xy * 5
J = 6xy(4z - 5)
K = 7a^2b + 4ab^2
K = ab * 7a + ab * 4b
K = ab(7a + 4b)
L = -6x^3 + 15xy
L = 3x * -2x^2 + 3x * 5y
L = 3x(-2x^2 + 5y)
