Answer:

[tex]15m^3-26m^2+11m-4[/tex]

Step-by-step explanation:

Find the product

[tex](5m^2 - 2m + 1)(3m - 4)[/tex]

Multiply both the parenthesis. Multiply each term inside the second parenthesis

[tex]5m^2 *3m + 5m^2*(-4) =15m^3-20m^2[/tex]

[tex]-2m * 3m + (-2m)(-4)= -6m^2 +8m[/tex]

[tex]1*3m +1(-4)=3m-4[/tex]

Collect all the terms together

[tex]15m^3-20m^2 -6m^2 +8m+3m-4[/tex]

Combine like terms

[tex]15m^3-26m^2+11m-4[/tex]
