y=3x^3-5x^2-11x-3的因式分解
可设分解结果为：(3x+a)(x²+bx+c)展开为：3x³+(a+3b)x²+(ab+3c)x+ac 对照分解前各项系数，可得如下方程：a+3b=-5 ab+3c=-11 ac=-3 解出这个方程，可得：a=1, b=-2, c=-3 所以 y=3x³-5x²-11x-3=(3x+1)(x²-2x-3) =(3x+1)(...
x^3-4x^2+5x-2=0因式分解,怎么分啊
x^3 - 4x^2 + 5x - 2 = 0 ( x^3 - 4x^2 + 4x ) + ( x - 2 ) = 0 x( x^2 - 4x + 4 ) + ( x - 2 ) = 0 x( x - 2 )^2 + ( x - 2 ) = 0 ( x - 2 )( x^2 - 2x + 1) = 0 ( x - 2 )( x - 1 )^2 = 0 所以，x = 1或x = 2....
