Answer 2

GIVEN ::- 3x² - 5x + 2k

The roots are real and equal.

TO FIND ::- the value of k

SOLUTION ::-

Comparing the given equation with ,

ax² + bx + c = 0

Here, a = 3 , b= -5 , c= 2k

As the roots are real and equal,

b² - 4ac = 0

(-5)² - 4(3)(2k) = 0

25 - 24k = 0

25 = 24 k

k. =. 25/24

k. = 5/2√6

Therefore the value of k is 5/2√6
