因式分解：5(x-y)^2+7(x-y)-6

网友回答

（5x-5y-3)x(x-y+2)
======以下答案可供参考======
供参考答案1:
5(x-y)^2+7(x-y)-6
=[5(x-y)-3] * [(x-y)+2]
供参考答案2:
5(x-y)^2+7(x-y)-6
5 21 -3所以=[5（x-y）-3] ×[（x-y）+2]
供参考答案3:
5(x-y)^2+7(x-y)-6
=[5(x-y)-3][(x-y)+2]
=(5x-5y-3)(x-y+2)
供参考答案4:
5(x-y)²+7(x-y)-6=[(x-y)+2][5(x-y)-3]=(x-y+2)(5x-5y-3)
供参考答案5:
原式=5(x-y)^2+7(x-y)-6
=[5(x-y)-3][(x-y)+2]
=(5x-5y-3)(x-y+2)
