Question

If xs 2 is a solution of a quadratic equation k+2r-3- 0, find the value
of 'k
​

Answer 1

Given quadratic equation

x^2 + 5x + k = 0

and we have been given roots are not equal. If roots are real then

So discriminant will be greater than zero.

D>0

=>b^2 - 4ac >0

=> (5)^2 - 4 (1)(k)>0

=>25 - 4k > 0

=> 4k<25

=>k<25/4

=>k<6.25 ANSWER
