分解因式:(x+3)(x+5)+x²-9分解因式:(x+3)(x+5)+x²-9分解因式:(x+3)(x+5)+x²-9(x+3)(x+5)+x²-9=(x+3
分解因式:(x+3)(x+5)+x²-9
分解因式:(x+3)(x+5)+x²-9
分解因式:(x+3)(x+5)+x²-9
(x+3)(x+5)+x²-9
=(x+3)(x+5)+(x+3)(x-3)
=(x+3)[(x+5)+(x-3)]
=(x+3)(2x+2)
=2(x+3)(x+1)
2(x+3)(x+1)
看来分解因式你很不擅长啊
(x+3)(x+5)+x²-9
=(x+3)(x+5)+(x+3)(x-3)
=(x+3)(x+5+x-3)
=(x+3)(2x+2)
=2(x+3)(x+1)
希望能够帮到你。
(x+3)(x+5)+x²-9
=(x+3)(x+5)+(x+3)(x-3)
=(x+3)(2x+2)
=2(x+3)(x+1)
2(x+1)(x+3)
