The tree died about 3357 years ago.
Explanation:
The half life of carbon - 14 is given by
where
Substituting these values in the above equation, we get,
Taking In on both sides of the equation, we get,
Since, only 66% of Carbon - 14 remains after the time T.
Thus, we have,
Taking In on both sides of the equation, we get,
Thus, the tree died about 3357 years ago.
The factors are 3x, 4x^2-3 and 5x+2
So, Option B, C and F are correct.
