Let a, b, and c be the roots of 24x^3 - 121x^2 + 87x - 8 = 0. Find \(\log_2 (a + b + c)\)
+2666 Vieta's formula states that the sum of all the roots of a polynomial is \(-{ b \over a} \)
Subbing in what we know, we find that the sum of the roots is \({121 \over 24}\).
Now, we just have to find the logarithm of this.
Can you take it from here?
