Question

find the value of k if x is equal to 4 is the solution of the equation 3 X square + kx - 2 is equal to zero​

Answer 1

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

Answer 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 ✌️
