Question

Find the value of K for which the quadratic equation 3x+2x+k=0has two equal roots.

Answer 1

Answer:

k = 1

6

Step-by-step explanation:

3x + 2x + k = 0

On comparing with ax²+ bx + c

a = 3 , b= 2 , c = k

For two equal root

D = 0

D = √b² - 4ac

0 = √2² - 4 × 3 × k

0 = √4 - 12k

12k = 2

k = 2

12

k = 1
