Question 41

If 2 is a root of the equation $$2x^2 + kx + 4 = 0$$, which of the following values of k givesanother positive integer root?

Solution

Since it is given that 2 is one of the roots of the equation,

Putting x=2 in the above equation

2(4) + 2k + 4=0

k= -6

Thus, the above equation will be in the form $$2x^2 - 6x + 4 = 0$$

Thus, the correct option is C.
