Question

The equation 2xᒾ +Kx +3 = 0 has 2 equal roots, then the value of K is : ​

Answer 1

Step-by-step explanation:

So, its Discriminant, D=0

D=k 2 −4(2)(3)=0

⟹k ^2 =24

⟹k= +√24 or -√24

Answer 2

Step-by-step explanation:

2x^2 +Kx + 3 = 0

2x ^2 + 2x +3x +3 = 0

2x ( x+2) + 3(x+2) = 0

(x+2)(2x+3) =0

x+2=0. 2x +3 = 0

x = -2. x =-3/2
