C Correct answer
Explanation

Equation: 4x^2 - 8x + 5 = 0. Sum of roots = -b/a = -(-8)/4 = 2.

AI explanation

First, arrange the equation 4x^2 + 5 - 8x = 0 into the standard form 4x^2 - 8x + 5 = 0. Using the sum of roots formula -b/a, we substitute a = 4 and b = -8. This gives -(-8)/4, which simplifies to 2.
