Correct option (C) -4
The sum of all the real values of x satisfying the equation 2(x - 1)(x2 + 5x - 50) = (1)0, we have
(x - 1)(x2 + 5x - 50) = 0
Therefore,
x - 1 = 0, x2 + 5x - 50 = 0
⇒ x = 1, x2 + 10x - 5x - 50 = 0
⇒ x(x + 10) - 5(x + 10) = 0
⇒ (x + 10) (x - 5) = 0
⇒ x = -10, 5
Therefore, the sum of all the real values of x, we get -10 + 5 + 1 = -4
