Question

if इस वन ऑफ द जीरो ​

Answer 1

k = 4/3

Step-by-step explanation:

Given:

-3 is one of the zero of above mentioned equation.

To find:

The value of k

What we have to do ?

Just substitute the zero in the equation and we will get our required answer.

Solution:

Putting the value of x as -3

$(k - 1) {x}^{2} + kx + 1 \\ \\ (k - 1)( - 3) {}^{2} + k( - 3) + 1 = 0 \\ \\ 9(k - 1) - 3k + 1 = 0 \\ \\9k - 9 - 3k + 1 = 0 \\ \\ 6k - 8 = 0 \\ \\ 6k = 8 \\ \\ k = \frac{8}{6} \\ \\ k = \frac{4}{3}$

Therefore the required value of k is 4/3.
