原式=-(30x^2m+11x^m-30)
==-(6m^x-5)(5m^x+6)
原式=x²+7x/12+49/576-49/576-1
=(x+7/24)²-625/576
=(x+7/24+25/24)(x+7/24-25/24)
=(x+4/3)(x-3/4)
原式=2(36x^4-25x²y²+4y^4)
=2[(6x²-2y²)-x²y²]
=2(6x²+xy-2y²)(6x²-xy-2y²)
=2((3x+2y)(2x-y)(3x-2y)(2x+y)
原式=[(x+y)+2][2(x+y)-3]
=((x+y+2)(2x+2y-3)
原式=2(x-y)²-3(x-y)-2
=[2(x-y)+1][(x-y)-2]
=(2x-2y+1)(x-y-2)
你说加分的
加100吧

30-11x^m-30x^2m ,x^2+7/12x-1 |x-2|-|x-m| m x平方-2x-m+1 因式分解(m-1)x-(x^2-m) 4^x+2^x-m 2x-3m x^2-（2m+1）x+m^2+m (x^2·x^m)^3/x^2m (x^2*x^m)^3/x^2m 若(x-m)(x-2)的积不含X,m=? (3x+1)(x-1)-（x+3)(5x-6)=-2x^2-11x+m,则m=? 计算(x+2)^m-1*(2+x)^m+1-(x+2)^2*(2+x)^2m x^2-2x+1-m^2为什么等于x-[1-m][x-[1+m]] x^(3)*x^(2m +1)*x^(m)=x^(31) 求m的值 x^2+(m+4)x+4m=0,为什么x=-4 x=-m 23m-17m=30 16x+4x+2x=264 32x-7x-5x=420的解方程 计算x^3m/(x^m-1)-x^2m/(x^m+1)-1/(x^m-1)+1(x^m+1) 9x^2-30x-m是完全平方式,求m
