Question

Determine k so that the equation 4x2 + kx + 1 = 0

Answer 1

Answer:

The value of k is -9/x.

Step-by-step explanation:

To find k:-

4×2 + kx + 1 = 0

8 + kx + 1 = 0

kx = -8 -1

k = -9/x

Therefore, the value of k is -9/x.

We can also verify our answer:-

4×2 + kx + 1 = 0

Substituting the value of k.

8 + -9/x × x + 1 = 0

9 - 9 = 0

0 = 0

Answer 2

Step-by-step explanation:

as we calculated above,

k= -9/x
