(6x^2-7x)^2-25因式分解...
(6x^2-7x)^2-25
＝(6x^2-7x)^2-5^2
＝(6x^2-7x+5)(6x^2-7x-5)
＝(6x^2-7x+5)(2x-5)(3x+1)
=(6x^2-7x+5)(6x^2-7x-5)
=(6x^2-7x+5)(2x+1)(3x-5)
(6x^2-7x)^2-25
= (6x^2-7x+5)(6x^2-7x-5)
= (6x^2-7x+5)(x-(7+13)/12)(x-(7-13)/12)
= (6x^2-7x+5)(x-5/3)(x+1/2)
= (1/6)(6x^2-7x+5)(2x-5)(3x+1)
(6x^2-7x)^2-25
=(6x^2-7x-5)^2
=(2x+1)^2(3x-5)^2
