Answer:
The answer is option 1.
Step-by-step explanation:
You have to use Distributive Laws,
![a(b + c) = ab + ac](https://tex.z-dn.net/?f=a%28b%20%2B%20c%29%20%3D%20ab%20%2B%20ac)
So for this question :
![(6r - 1)( - 8r - 3)](https://tex.z-dn.net/?f=%286r%20-%201%29%28%20-%208r%20-%203%29)
![= 6r( - 8r) + 6r( - 3) - 1( - 8r) - 1( - 3)](https://tex.z-dn.net/?f=%20%3D%206r%28%20-%208r%29%20%2B%206r%28%20-%203%29%20-%201%28%20-%208r%29%20-%201%28%20-%203%29)
![= - 48 {r}^{2} - 18r + 8r + 3](https://tex.z-dn.net/?f=%20%3D%20%20-%2048%20%7Br%7D%5E%7B2%7D%20%20-%2018r%20%2B%208r%20%2B%203)
![= - 48 {r}^{2} - 10r + 3](https://tex.z-dn.net/?f=%20%20%3D%20%20-%2048%20%7Br%7D%5E%7B2%7D%20%20-%2010r%20%2B%203)
