SOLUTION:-

Answer

• k= 1/8

Given

• Quadratic equation = 2x²-x+k=0

To Calculate

• Value of k

Explanation

The Given equation is 2x²-x+k=0

This is of the form of ax²+bx+c=0

Where

a = 2

b = -1

c = k

We know that,

D = b²-4ac

Putting values

➡️ (-1)²-4×2×k

➡️ 1- 8k

For real and equal roots

We much have,

D = 0

➡️ D= 0

➡️ 1-8k=0

➡️ -8k=-1

➡️ k= -1/-8

➡️ k= 1/8

Hence,

1/8 are the required value of k
