Answer:

[tex]-8m^5+10m^4+9m^3-16m^2+5m[/tex]

Step-by-step explanation:

Kinda a long one!

[tex](-2m^3+3m^2-m)(4m^2+m-5)[/tex]

Multiply the second parenthases by each term in the first parentheses:

[tex]-2m^3(4m^2+m-5)+3m^2(4m^2+m-5)-m(4m^2+m-5)[/tex]

Distribute [tex]-2m^3[/tex] through the parentheses:

[tex]-8m^5-2m^4+10m^3+12m^4+3m^3-15m^2-4m^3-m^2+5m[/tex]

Collect like terms and you get your answer:

[tex]-8m^5+10m^4+9m^3-16m^2+5m[/tex]

Hope this helps!! :)
