Question

The equation 2X^2-kx+3=0 has 2 equal roots, then the value of k is

+√6
+4
+3√2
+2√6

Tell me the correct answer quickly.....​

Answer 1

Answer:

+2√6 is the answer

Step-by-step explanation:

The formula for two equal roots is b^2-4ac=0

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

According to formula

-k^2-4×2×3=0

k^2-24=0

k^2=24

k=√24

24=2×2×2×3

k=2√6
