Answer:
- 23
Step-by-step explanation:
We could do this the long way and expand the whole product or note that the terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is
4a³ × 3a = 12
+ 5a² × - 7a² = - 35
Summing gives
12 - 35
= - 23
with coefficient - 23
