因式分解:(x-5)(x+5)-(x+1)(x+5)因式分解:(x-5)(x+5)-(x+1)(x+5)因式分解:(x-5)(x+5)-(x+1)(x+5)原式=(x+5)[(x-5)-(x+1)]=

因式分解:(x-5)(x+5)-(x+1)(x+5)
因式分解:(x-5)(x+5)-(x+1)(x+5)

因式分解:(x-5)(x+5)-(x+1)(x+5)
原式= (x+5)[(x-5)-(x+1)]
=(x+5)(x-5-x-1)
=-6(x+5)

(x-5)(x+5)-(x+1)(x+5)
=(x+5)(x-5-x-1)
=-6(x+5)

原式= (x+5)[(x-5)-(x+1)]
=(x+5)(x-5-x-1)
=-6(x+5)
