Question

find the value of k if 2x-1 is a factor of 4x²+kx+1 hence find the order factor​

Answer 1

Answer:

k=-4

Step-by-step explanation:

2x-1 is a factor of 4x²+kx+1

Let p(x)=4x²+kx+1

As 2x-1 is factor of p(x), p(½)=0

So,4×(½)²+k×(½)+1=0

or, 1+k/2+1=0

or, k/2+2=0

or, (k+4)/2=0

or, k+4=0×2

or, k=-4

Hence, k=-4
