(8x四次方-6x三次方-4x平方 10x)

x^4-x^3-5x^2-6x-4=(x^2+ax+b)(x^2+cx+d)=x^4+(a+c)x^3+(ac+b+d)x^2+(ad+bc)x+bd由于x的相同次数的项的系数要相等所以a+c=-1,

若f(x)=-8a平方x平方+6a三次方x三次方-4a四次方x四次方,=-2ax^2(4a-3a^2x+2a^3x^2)f(x)除以（-4ax平方）=-2ax^2(4a-3a^2x+2a^3x^2)除

(2x³y-1/2x²y-3/2)×4x的平方y的三次方=8x的五次方y的四次方-2x的四次方y的四次方-6x的平方y的立方

x^4+4*x^3+8*x^2-16*x-48分解因式为：(x-2)*(x+2)*(x^2+4*x+12)所以答案为：(x-2)*(x+2)

5X²-2=（√5x+√2)(√5x-√2)x四次方-4x²+4=(x²-2)²=(x+√2)²(x-√2)²x四次方+2x²-8

∵x平方加4x=1;(x+2)^2=5∴x=±√5-2∴x五次方+6x四次方+7x三次方-8x+1=x^5+4x^4+2x^4+8x^3-x^3-8x+1=x^3(x^2+4x)+2x^2(x^2+4

x^4+7x^3+8x^2+7x+1=x^4+x^3+x^2+6x^3+6x^2+6x+x^2+x+1=x^2(x^2+x+1)+6x(x^2+x+1)+(x^2+x+1)=(x^2+x+1)(x^2

x^4-x^3-5x^2-6x-4=(x^2+ax+b)(x^2+cx+d)=x^4+(a+c)x^3+(ac+b+d)x^2+(ad+bc)x+bd由于x的相同次数的项的系数要相等所以a+c=-1,

雨后泪樱花,1、x^3-6x^2+9x=x(x^2-6x+9)=x(x-3)^22、-x^4+8x^2-16=-(x^4-8x+16)=-(x^2-4)^2=-(x+2)^2(x-2)^2

x四次方-6x三次方+9x二次方分之x二次方-3x=x(x-3)/x²（x²-6x+9）=(x-3)/x(x-3)²=1/x(x-3)=1/(x²-3x)如追加

x四次方-3x三次方-8x平方+6x+4=0(x^4+x^3-2x^2)-4x^3-4x^2+8x-2x^2-2x+4=0x^2(x^2+x-2)-4x(x^2+x-2)-2(x^2+x-2)=0(x

x四次方+3x三次方-6x-4=(x^4-4)+3x(x^2-2)=(x^2-2)(x^2+2)+3x(x^2-2)=(x^2-2)(x^2+2+3x)=(x+1)(x+2)(x^2-2)祝学习进步

x^4+4x^3+4x^2-9=x^2(x^2+4x+4)-9=x^2(x+2)^2-9=[x(x+2)]^2-9=(x^2+2x)^2-9=(x^2+2x+3)(x^2+2x-3)=(x^2+2x+

x4+2x3-9x2-2x+8=0,发现x=1是方程的根,（x4+2x3-9x2-2x+8）/（x-1）=x3+3x2-6x-8x3+3x2-6x-8=0,发现x=2是方程的根,（x3+3x2-6x-

x^4+4x^3+3x^2+4x+2=x^4+x^2+4x^3+4x+2x^2+2=x^2(x^2+1)+4x(x^2+1)+2(x^2+1)=(x^2+1)(x^2+4x+2)

-8x四次方y+6x三次方y²-2x三次方y=-2x³y(4x-3y+1)

4x^4/x^2=4x^26x^5/x^3=6x^28x^6/x^4=8x^2

x^2(x^2-4x+4)-x^2+4x-4=0(x(x-2))^2-(x-2)^2=0x^2-3x+2=0x=1,2x^2-x-2=0X=2,-1

17x的9次方,上式为2x的9次方-64x的9次方+81x的9次方

顺便说一下,我算的算式是x^4-(2*x)*(2*x)*(2*x)+2^x=4共4个根,都是一样复杂,我给你贴了其中一个.
