in this you have to put the value of k so the value of k is 1so your equation is looks like. X2+1x+3=0the solve it hope it's correct

Mmgg: Plz do step by step

p(x) = (2k - 1)x^2 + kx + 3 = 0
        = (2k - 1)x^2 + kx + 3 = 0
     
 D ^2 = 4 ac
         = 4 * 2k -1 * 3
        = 4* 6k - 3
          = 24k - 12
lets take D = 0
    24k = 12
 k = 12 / 24
 k =    1 / 2

                       

Mansi1541: from where d and ac
Strangercitizen1525: d utakeit as the determinant and a and c are the coefficient
Mmgg: between 2k-1 and 2 that is not multiply sign but that is x alphabet.plz solve again
Mmgg: Plz help
Strangercitizen1525: dude the ans is same
Strangercitizen1525: i modified it
Mmgg: The ans is except 1/2 not equal to 1/2.
