The value of k for which the quadratic equation 2x² + kx + 3 = 0 has equal roots is:
For equal roots k² = 24 To determine k when roots are equal we can apply the condition b² = 4ac Here a = 2 b = k c = 3 k² = 4(2)(3) k² = 24 k = ±√24 k = ±2√6 As k = -6 is provided as an option k = -6 is the answer Thus the value of k for which the quadratic equation 2x² + kx + 3 = 0 has equal rootsRead more
For equal roots k² = 24
To determine k when roots are equal we can apply the condition b² = 4ac
Here a = 2 b = k c = 3
k² = 4(2)(3)
k² = 24
k = ±√24
k = ±2√6
As k = -6 is provided as an option
k = -6 is the answer
Thus the value of k for which the quadratic equation 2x² + kx + 3 = 0 has equal roots is -6.

The roots of the quadratic equation x² – 5x + 6 = 0 are:
For quadratic equation x² - 5x + 6 = 0 Let's solve using factorization method: x² - 5x + 6 = 0 x² - 2x - 3x + 6 = 0 x(x - 2) - 3(x - 2) = 0 (x - 2)(x - 3) = 0 Therefore x = 2 or x = 3 The roots of the equation are 2 and 3. Hence option "2, 3" is correct. We can verify: When x = 2: 2² - 5(2) + 6 = 4Read more
For quadratic equation x² – 5x + 6 = 0
Let’s solve using factorization method:
x² – 5x + 6 = 0
x² – 2x – 3x + 6 = 0
x(x – 2) – 3(x – 2) = 0
(x – 2)(x – 3) = 0
Therefore x = 2 or x = 3
The roots of the equation are 2 and 3.
Hence option “2, 3” is correct.
We can verify:
When x = 2: 2² – 5(2) + 6 = 4 – 10 + 6 = 0
When x = 3: 3² – 5(3) + 6 = 9 – 15 + 6 = 0
