Answer:
11. 10x^2 - 13x - 3
12. 5x^2 + 18x + 5
Step-by-step explanation:
11. Product means multiplication, so you can multiply (5x + 1) and (2x - 3).
- Using the FOIL (First+Outer+Inner+Last)
So: 
12.
(So, you distribute the 2 to x^2 + 5x + 30, then combine like terms).

Hopefully, this helped you. Good luck & have a good day!
