Question

Roots of quadratic equation are equal and real the equation is 2 x square + kx + 3 find the k

Answer 1

Answer:

k = + 2√6  or k = - 2√6

Step-by-step explanation:

The given equation is 2x² + kx + 3 = 0

Here a = 2, b = k and c = 3

For equal roots, D = 0

So,

b² - 4ac = 0

Therefore,

k² - 24 = 0

k = √24

k = + 2√6  or k = - 2√6
