Answer:

I think I helped u.

Step-by-step explanation:

• $3a(a - 4b + 5c) \\ = > 3a \times a + 3a \times ( - 4b) + 3a \times 5c \\ = > {3a}^{2} - 12ab + 15ac$
• $4a(10c - 3b + 2a) \\ = > 4a \times 10c + 4a \times ( - 3b) + 4a \times \times 2a \\ = > 40ac - 12ab + {8a}^{2}$

4a -12ab +8a²

15ac -12ab +3a²
