Question

the discriminant of quadratic equation 3x2-4x-2=0 is equal to​

Answer 1

$Compare \: given \: Quadratic \:equation$

$3x^{2} - 4x - 2 = 0 \: with \: ax^{2}+bx+c=0 ,$

$we \:get$

$a = 3 , b = -4 \:and \: c = -2$

$\red{ Discreminant } = b^{2} - 4ac$

$= (-4)^{2} - 4 \times 3 \times (-2)$

$= 16 + 24$

$= 40$

Therefore.,

$\red{ Discreminant } \green { = 40}$
