问题描述:
因式分解3x-12x^3
答
3x-12x^3=3x(1-4x^2)=3x(1+2x)(1-2x)
答
原式=3x(1-4x^2)=3x(1+2x)(1-2x)
答
3x-12x^3
=3x(1-4x^2)
=3x(1-2x)(1+2x)
答
原式=-3x(4x^2-1)
=-3x(2x+1)(2x-1)
答
3x(1+2x)(1-2x)
答
=3x(1-4x^2)
=3x(1+2x)(1-2x)
答
3x-12x^3
=3X(1-4X²)
=3X(1+2X)(1-2X)
答
3x-12x^3
=3x(1-4x^2)
=3x(1+2x)(1-2x)
答
3x-12x^3
=3*(x-4x^3 )
=3*x(1-4x^2 )
=3*x(1-2x )(1+2x)
