The sum of the roots of the quadratic equation 3x2 – 9x + 5 = 0 isa)3...
Solution:
Given quadratic equation is 3x^2 - 9x + 5 = 0
We know that the sum of the roots of a quadratic equation ax^2 + bx + c = 0 is given by -b/a.
Here, a = 3 and b = -9.
Sum of roots = -b/a = -(-9)/3 = 9/3 = 3
Hence, the sum of the roots of the given quadratic equation is 3.
Therefore, option (C) is the correct answer.
