Question

(5m2 - 2m + 1)(3m - 4)

Answer 1

What is the product?

Answer 2

first multiply one by one:
3m(5m²)-3m(2m)+3m-4(5m²)+4(2m)-4

and then do the actual multiplying:
15m^3-6m^2+3m-20m^2+8m-4

(I hope you can see that :3 ^ means to the power of btw)
So next arrange all the in unknowns starting from largest to numbers:
15m^3-6m^2-20m^2+3m+8m-4

And then add/subtract the unknowns that have the same power:
15^3-26m^2+11m-4

Voila! :D
