Step-by-step explanation:
3x² + kx - 2 = 0
x = 4 रखने पर
3(4)² + k(4) - 2 = 0
3(16) + 4k - 2 = 0
48 + 4k - 2 = 0
4k + 46 = 0
4k = -46
k = -46/4 = -23/2

Step-by-step explanation:
given :-
x = 4
find = k
so, we put the value of x in the equation
3x^2 + kx - 2 = 0
3(4)^2 + k× 4 - 2 =0
3×16 + 4k- 2 =0
48 + 4k - 2 = 0
46 + 4k =0
4k = - 46
k = -46/4
k = - 23/2
hope u get ✌️
