Answer:
[tex]4x\left(x^2-3x+1\right)[/tex]
[tex]Distribute\:parentheses[/tex]
- [tex]=4xx^2+4x\left(-3x\right)+4x\cdot \:1[/tex]
[tex]\mathrm{Apply\:minus-plus\:rules}[/tex]
- [tex]+\left(-a\right)=-a[/tex]
- [tex]=4x^2x-4\cdot \:3xx+4\cdot \:1\cdot \:x[/tex]
[tex]Simplify[/tex]
- [tex]=4x^3-12x^2+4x[/tex]
