Question

Find values of k for which the quadratic equation 3x2 – kx + 3k = 0 has equal roots.

Answer 1

Discriminant = b² - 4ac

=> (-k)² - 4(3)(3k)
=> k² - 36k

We Know, equal roots,, discriminant =0

So,

=> k² - 36k = 0
=> k(k - 36) = 0
k = 0 or 36

Answer 2

Answer:

Step-by-step explanation:3x2+kx+3=0

Let a=3 b=k and c= 3

By quadratic equation

B2-4ac=0

K2-4ac=0

K2-4*3*3=0

K2-36=0

K2=36

K=6

The value of k is 6

And K2 means k Square and B2 means b square
