Answer:
The polynomial is not a quadratic equation, so you cannot use the standard method to solve for x. To solve for r, we'll use the box method.
Starting with the left side of the equation, we have:
2r(t+6) = 0
Distribute the 2r:
2rt + 2r * 6 = 0
Combine like terms:
2rt + 12r = 0
Now, we have a linear equation that we can solve for r:
12r + 2rt = 0
Subtract 2rt from both sides:
12r = -2rt
Divide both sides by 10:
r = -t/6
So, r is equal to -t/6.
Hope this helps!
