Answer:
[tex]-6x^5+8x^4-14x^3[/tex]
Step-by-step explanation:
[tex]-2x^3(3x^2-4x+7)[/tex] Use distributive property
[tex]-2x^3[/tex] · [tex]3x^2[/tex] = [tex]-6x^5[/tex]
[tex]-2x^3[/tex] · [tex]-4x[/tex] = [tex]8x^4[/tex] Product becomes positive because of two negatives
[tex]-2x^3[/tex] · [tex]7[/tex] = [tex]-14x^3[/tex]
Group all of those numbers together (in order)
[tex]-6x^5+8x^4-14x^3[/tex]
