因式分解x^4+4x^3+6x^2+4x+1因式分解x^4+4x^3+6x^2+4x+1因式分解x^4+4x^3+6x^2+4x+1x^4+4x^3+6x^2+4x+1=(x^4+4x³+3

因式分解x^4+4x^3+6x^2+4x+1
因式分解x^4+4x^3+6x^2+4x+1

因式分解x^4+4x^3+6x^2+4x+1
x^4+4x^3+6x^2+4x+1
=(x^4+4x³+3x²)+(3x²+4x+1)
=x²(x²+4x+3)+(x+1)(3x+1)
=x²(x+1)(x+3)+(x+1)(3x+1)
=(x+1)(x³+3x²+3x+1)
=(x+1)[(x³+1)+(3x²+3x)]
=(x+1)[(x+1)(x²-x+1)+3x(x+1)]
=(x+1)(x+1)(x²-x+1+3x)
=(x+1)²(x²+2x+1)
=(x+1)²(x+1)²
=(x+1)^4
