Question

what is discriminant of 4X2 - 3x - 1 =0?​

Answer 1

Answer:

19

Step-by-step explanation:

given a quadratic equation $ax^{2} +bx+c =0$, the discriminant value is given by $b^{2} -4ac$

here, we have 4x²-3x-1 = 0

=> a =4; b= -3 ; c = -1

hence the discriminant value is,

 -(-3) - 4(4)(-1)

= 3+16

= 19
