x^2-4x=x(x-4)
啊,等图片再答:再答:望采纳!
x(x3x2x1)
x(x-y)+4(y-x)=x(x-y)-4(x-y)=(x-y)(x-4)=(x-y)(X+2)(X-2)
1.x^3-5x+4=x^3-x^2+x^2-x-4x+4=(x-1)(x^2+x-4)2(y^2-3y-2)(y^2-3y+4)-16=(y^2-3y)^2+2(y^2-3y)-24=(y^2-3y
x^4-x^-2-x+1=x²(x²-1)-(x-1)=(x-1)[x²(x+1)-1】=(x-1)(x³+x²-1);
1、原式=x³-x+2x-2=x(x+1)(x-1)+2(x-1)=(x-1)(x²+x+2)2、原式=x³-2x²+2x²-2x-4=x²
设该式为x^3+ax^2+bx+c=x^2(x+a)+b(x+c/b)因为能分解能三个一次式之积,所以有a=c/b,即c=ab该式继续分化,有(x^2+b)(x+a)因为要x^2+b能分解成两个一次式
(1+x+x^2+x^3)^2-x^3设y=1+x+x^2,则(x^3-1)=(x-1)*(1+x+x^2)=(x-1)*y,原式=(y+x^3)^2-x^3=y^2-2*y*x^3+x^6-x^3=
LS你没有写对(X+1)(X^4-X^3+X^2+1)=1+X+X^2+X^5楼主的那个题目如果是:x^5-x^4+x^3+x^2+1没有因式得提拉
x^4-4x^3+4x^2-1=x^4-x^3-3x^3+3x^2+x^2-1=x^3(x-1)-3x^2(x-1)+(x+1)(x-1)=(x-1)(x³-3x²+x+1)=(x
x3-x=x(x2-1)=x(x+1)(x-1);a2+4a+4=(a+2)2;4x2-25=(2x+5)(2x-5);9x2-y2-4y-4=9x2-(y+2)2=(3x+y+2)(3x-y-2).
1、a的五次方+a+1=(a^5-a^2)+(a^2+a+1)=a^2(a^3-1)+(a^2+a+1)=a^2(a-1)(a^2+a+1)+(a^2+a+1)=(a^2+a+1)(a^2(a-1)+
x5-x4+x3-x2+x-1=x4(x-1)+x2(x-1)+(x-1)=(x-1)(x4+x2+1)=(x-1)(x4+2x2+1-x2)=(x-1)[(x2+1)2-x2]=(x-1)(x2+x
x³-x²-x-1=(x³-x)-(x+1)=x(x²-1)-(x+1)=x(x+1)(x-1)-(x+1)=(x²-x-1)(x+1)
不明白X3是什么意思
(x-1)(x^2+ax+2)=x^3+ax^2+2x-x^2-ax-2=x^3+(a-1)x^2+(2-a)x-2=0a-1=-12-a=-1不合理(x-2)(x^2+ax+1)=x^3+ax^2+
原式=(X^4-2^3)+(3X^3-6X^2)-(3X^2-6X)+(X-2)=X^3(X-2)+3X^2(X-2)-3X(X-2)+(X-2)=(X-2)(X^3+3X^2-3X+1)
x3-x2+1/4x=x(x²-x+1/4)=x(x-1/2)²很高兴为您解答,【the1900】团队为您答题.请点击下面的【选为满意回答】按钮,
