要过程

原式=x^4+5x-16+10
=(x^4-16)+(5x+10)
=(x^2+4)(x^-4)+5(x+2)
=(x^2+4)(x+2)(x-2)+5(x+2)=(x+2)((x^2+4)(x-2)+5)
=(x+2)(x^3-2x^2+4x-8+5)
=(x+2)(x^3-2x^2+4x-3)
=(x+2)(x^3-2x^2+x+3x-3)
=(x+2)(x(x^2-2x+1)+3(x-1))
=(x+2)(x(x-1)^2+3(x-1))
=(x+2)(x-1)(x(x-1)+3)
=(x+2)(x-1)(x^2-x+3)

在实系数范围内只能分解到这一步了,你满意吗?

(x-1)(x+2)(x^2-x+3)

(x+3)(x+4)(x+5)(x+6)=8 x^6+x^5+x^4+x^3+x^2+x+1=0 1x 2x 3x 4x 5x 6=( )x( )+( ) (X-1/X)=5,且X<0,求x^10+x^6+x^4+1除以x^10+x^8+x^2+1的值 X^6-X^5+20X^4-2=0 (x+1)(x-4)-6=x^2-3x-4-6=x^2-3x-10=(x+2)(x-5)中x^2-3x-10怎么弄成(x-5)(x+2). x^4+5x-6=? x-5/x-7+x-2/x--4=x-3/x-5+x-4/x-6 解因式方程：x-4/x-5+x-8/x-9=x-7/x-8+x-5/x-6 (x+2/x+1)+ (x+6/x+5)=(x+3/x+2)+(x+5/x+4)怎么解?
