Question

Select the correct product. (5m2 - 2m + 1)(3m - 4) 15m3 - 26m2 + 5m - 4 15m3 - 26m2 + 11m - 4 15m3 - 14m2 + 11m + 4 15m3 - 14m2 - 5m - 4

Answer 1

15m3 - 26m2 + 11m - 4

Answer 2

`15m^3-26m^2+11m-4`

Explanation:

Find the product

`(5m^2 - 2m + 1)(3m - 4)`

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

`5m^2 *3m + 5m^2*(-4) =15m^3-20m^2`

`-2m * 3m + (-2m)(-4)= -6m^2 +8m`

`1*3m +1(-4)=3m-4`

Collect all the terms together

`15m^3-20m^2 -6m^2 +8m+3m-4`

Combine like terms

`15m^3-26m^2+11m-4`
