Question

3. If the roots of the quadratic equation x? + 6x + k = 0 are equal, then the value
of `k´ is​

Answer 1

Step-by-step explanation:

• $\leqslant$

Answer 2

Step-by-step explanation:

The roots of Quadratic Equation have Equal Roots

i.e., b²-4ac = 0

b = 6, a = 1, c = k

Now, b²-4ac = 0

=> (6)² - 4×1×k = 0

=> 36 - 4k = 0

=> -4k = -36

=> k = 9.
