a^2 - b^2 = (a - b)(a + b)
Bonjour
Factoriser :
x^2 - 16 =
= x^2 - 4^2
= (x - 4)(x + 4)
x^2 - 1 =
= x^2 - 1^2
= (x - 1)(x + 1)
4 - x^2 =
= 2^2 - x^2
= (2 - x)(2 + x)
100 - y^2 =
= 10^2 - y^2
= (10 - y)(10 + y)
169 - b^2 =
= 13^2 - b^2
= (13 - b)(13 + b)
0,01 - a^2 =
= 0,1^2 - a^2
= (0,1 - a)(0,1 + a)
