Question

Discriminant of the following quadratic equation is :
$2x^2$ - 5x + 3 = 0

Answer 1

$\Rightarrow$ The given quadratic equation is $2x^2-5x+3=0$, comparing it with $a{x}^2+bx+c=0$

$\Rightarrow$ We get, $a=2,b=-5$ and $c=3$

$\Rightarrow$ $D=b^2-4ac$

$=(-5{)}^2-4(2\left)\right(3)$

$=25-24$

$=1$

$\therefore$ Discriminant of given quadratic equation is $1$.
