4×(2x²-3x+2)×-2×(4x²-2x+3),这道题用方程解,急
解方程:x(6-x)-2x(x+1)-(x^3-3x^4)/x²=4
解方程 (3x+1)(3x-1)=(x+2)(9x-4) 2(x-3)(x-2)-(x+3)²=(x-1)(x
解方程:1.x/x+1-1=3/(x+1)(x-2) 2.3/x+2+1/x=4/x²+2x 3.2/3+x/
解方程:4x²+2x+3/2x+1 = 2x²-2x+1/x-1
解方程2X(X-3)-x(4-3X)=5X²-3X+2
解方程(x²-x+4)x-(x-1)(x²+2)=x+7
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
