Question

3) Find the value of k for the quadratic equation so that it has two equal roots:
2x7kx + 3 =0​

Answer 1

Answer:

For getting 2 equal roots the condition has to be that the Discriminant which is b²-4ac should be = 0.

Step-by-step explanation:

7k²-4×2×3=0

49k²-24=0

49k²=24

k²=24/49

k= √24/49

k= 2√6/7

thus k = 2√6/7
