(x-2y)^2-2(x-2y)-24 因式分解
(x-2y)^2-2(x-2y)-24 因式分解

(x-2y)^2-2(x-2y)-24 因式分解
(x-2y)^2-2(x-2y)-24
十字相乘法
1 4
1 -6
所以原式=(x-2y+4)(x-2y-6)

(x-2y-6)(x-2y+4)

(x-2y)^2-2(x-2y)-24
=(x-2y-6)(x-2y+4)

十字相乘法

x^4-13x^2+36 =(x^2-4)(x^2-9) (x-2y)^2-2(x-2y)-24 = (x-2y+4)(x-2y-6) 7x^2-2xy-5y^2 ==(7x+5y)(x-y) 2x^3+
