✔ 最佳答案
75^2 - 108= (3 x 25)^2 - (9 x 12)
= (3)^2(25)^2 - (9 x 12)
= (9 x 625) - (9 x 12)
= 9(625 - 12)

nothing to factor, it's just a number

75^2 = 3*3*5*5*5*5
108 = 2*6*3*3
75^2-108 = 3^2(625 - 12) = 3^2(613) = 3*3*613
613 must be prime, because 625 and 12 have no more common factors, so that is the complete factorization.
108 = 2*6*3*3
75^2-108 = 3^2(625 - 12) = 3^2(613) = 3*3*613
613 must be prime, because 625 and 12 have no more common factors, so that is the complete factorization.

75^2 =(3^2)(25^2)
108 = (4*9)(3)
You can take out a 9: from 75 and 108:
75^2 - 108 = 9(25^2 - 12)
108 = (4*9)(3)
You can take out a 9: from 75 and 108:
75^2 - 108 = 9(25^2 - 12)
