what is the product? (6r - 1)(-8r - 3) -48r² - 10r + 3 -48r² - 10r - 3 -48r² + 3 -48r² - 3

Explanation:

Step1: Use FOIL method

$(6r - 1)(-8r-3)=6r\times(-8r)+6r\times(-3)+(-1)\times(-8r)+(-1)\times(-3)$

Step2: Calculate each product

$6r\times(-8r)=-48r^{2}$, $6r\times(-3)=-18r$, $(-1)\times(-8r) = 8r$, $(-1)\times(-3)=3$

Step3: Combine like - terms

$-48r^{2}-18r + 8r+3=-48r^{2}+(-18r + 8r)+3=-48r^{2}-10r + 3$

Answer:

$-48r^{2}-10r + 3$
