Answer:
The required product is [tex]-48r^2-10r+3[/tex]
Step-by-step explanation:
Consider the provided expression.
[tex](6r-1)(-8r-3)[/tex]
Open the parentheses.
[tex]6r\left(-8r\right)+6r\left(-3\right)+\left(-1\right)\left(-8r\right)+\left(-1\right)\left(-3\right)[/tex]
[tex]-6\cdot \:8rr-6\cdot \:3r+1\cdot \:8r+1\cdot \:3[/tex]
[tex]-48r^2-18r+8r+3[/tex]
Add the like terms.
[tex]-48r^2-10r+3[/tex]
Hence, the required product is [tex]-48r^2-10r+3[/tex]
