因式分解:x^2 -12xy+36y^2 - x + 6y (x-6y)(x-6y-1)

因式分解:x^2 -12xy+36y^2 - x + 6y (x-6y)(x-6y-1)
因式分解:x^2 -12xy+36y^2 - x + 6y (x-6y)(x-6y-1)

因式分解:x^2 -12xy+36y^2 - x + 6y (x-6y)(x-6y-1)
x^2 -12xy+36y^2 - x + 6y
=(x-6y)²-(x-6y)
=(x-6y)(x-6y-1)

x^2 -12xy+36y^2 - x + 6y
=(x-6y)^2-(x-6y)
=(x-6y)(x-6y-1)
就是这样来的
