6x的四次方加5x的立方加3x^2减3x减二分解因式
6x的四次方加5x的立方加3x^2减3x减二分解因式
6x⁴+5x³+3x²-3x-2
=6x⁴+3x³+2x³+x²+2x²+x-4x-2
=3x³(2x+1)+x²(2x+1)+x(2x+1)-2(2x+1)
=(2x+1)(3x³+x²+x-2)
=(2x+1)【(3x³-2x²)+(3x²-2x)+(3x-2)】
=(2x+1)【x²(3x-2)+x(3x-2)+(3x-2)】
=(2x+1)(3x-2)(x²+x+1)
x的四次方加3x的立方减3x的平方减11x减6因式分解

9x的四次方减3x的立方加7x的平方减3x减2因式分解
9x的4次方-3x的立方+7x的平方-3x-2
=9X^4-3X^3-2X^2+9X^2-3X-2
=(X^2+1)(9X^2-3X-2)
=(X^2+1)(3X-2)(3X+1)
x的四次方加2x的三次方加6x的平方加5x减14等于因式分解
x⁴+2x³+6x²+5x-14
=(x⁴+2x³)+(6x²+5x-14)
=x³(x+2)+(6x-7)(x+2)
=(x+2)(x³+6x-7);

x的四次方减4x的三次方加2x二次方加4x减3分解因式
x的四次方减4x的三次方加2x二次方加4x减3
=x^4-4x^3+2x^2+4x-3
=x^4-x^3-3x^3+3x^2-x^2+x+3x-3
=(x^4-x^3)-(3x^3-3x^2)-(x^2-x)+(3x-3)
=x^3(x-1)-3x^2(x-1)-x(x-1)+3(x-1)
=(x-1)(x^3-3x^2-x+3)
=(x-1)[(x^3-3x^2)-(x-3)]
=(x-1)[x^2(x-3)-(x-3)]
=(x-1)(x-3)(x^2-1)
=(x-1)(x-3)(x+1)(x-1)
=(x-1)^2(x-3)(x+1)
求多项式x的平方减3x立方加二减5x的四次方与4s的四次方减x减六减3x的立方的差
(x^2-3x^3+2-5x^4)-(4x^4-x-6-3x^3)
=x^2-3x^3+2-5x^4-4x^4+x+6+3x^3
=-9x^4+x^2+x+8
