To do this, you multiply each term in one polynomial by all the terms in the other polynomial...so that
(x + 5)(2x^2 + 7x - 10) =
First multiply all three terms by x and get
2x^3 + 7x^2 - 10x
Then multiply all three terms by 5 and collect them all...
+ 10x^2 + 35x - 50
The answer is the sum of all of these...
2x^3 + 17x^2 + 25x - 50
