Answer:

The answer to your question is letter B

Step-by-step explanation:

Product

                     (6m² - 5m + 4) ( -4m² - 3m - 7)

1.- Multiply -4m² by each term of the first  group

           ( 6m² - 5m + 4)(-4m²) = -24m⁴ + 20m³ - 16 m²

2.- Multiply -3m by each term of the first group

          (6m² - 5m + 4) (-3m) = -18m³ + 15m² - 12m

3.- Multiply -7 by by each term of the first group

         (6m² - 5m + 4) (-7) = -42m² + 35m - 28      

4.- Simplify

      -24m⁴ + 20m³ - 16 m²  -18m³ + 15m² - 12m -42m² + 35m - 28      

     -24m⁴ + 2m³ - 43m² + 23m - 28

       

 

Answer:

-24m⁴ + 2m³ - 43m² + 23m - 28
