24x^2-50x+24=0 ,

X(X+1)(X+2)=24 =(x^2-5x)^2+10(x^2-5x)+24 =x^4-10x^3+25x^2+10x^2-50x+24 这是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=（x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24 =（x^2-5x+4)(x^2-5x+6) =(x^2-5x)^2+10(x^2-5x)+24 是怎么转化的(X-1)(X-2)(X-3)(X-4) =(X-1)(X-4) (X-2)(X-3)=（x^2-5x+4)(x^2-5x+6)=(x^2-5x)^2+10(x^2-5x)+24=x^4-10x^3+25x^2+10x^2-50x+24=x^4-10x^3+35x^2-50x+24不好意思我弄错了，是=（x^2-5 X^3-7X^2+18X-24=0 -x^3-3x^2+10x+24=0 x^4-5x^2+10x+24=0 一元二次方程解答!x（5x+4）=5x+44x^2-45=31x-3x^2+22x-24=0(x+8)(x+1)= -12(3x+2)(x+3)=x+14 给50分 今天就要用分式法x^+10X+16=0 16x^-24x+9=0 x^2-4根号2x+9=0 3x^2+10=2x^2+8x x^2+14x-24=0 x^2-25x+24=0 x^2-10x-24=0 （X^+X)(X^+X-14)+24=0 ^代表平方 x*x+2x=24 ,x=? 解方程（x²+3x+2)(x²-2x-1)(x²-7x+12)+24=0 x×x--2x=24 x等于多少? (x+1)(x+2)(x+3)(x+4)=24 2x乘以x乘以x=24,求x! (x+1)(x+2)(x+3)(x+4)=24
