方程x^3-5*x^2+8*x-4=0化简
x³ - 5x² + 8x - 4 = 0
( x³ - x² ) - (4x² - 4x) + (4x - 4) = 0
x²(x-1) - 4x(x-1) +4(x-1) = 0
(x-1)(x² - 4x+4) = 0
(x-1)(x - 2)² = 0
x=1 或 x=2
( x³ - x² ) - (4x² - 4x) + (4x - 4) = 0
x²(x-1) - 4x(x-1) +4(x-1) = 0
(x-1)(x² - 4x+4) = 0
(x-1)(x - 2)² = 0
x=1 或 x=2
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
方程(x+1)(x+2)(x+3)(x+4)(x+5)(x+6)(x+7)(x^2+8x+9)+64=0
