Question

Without determining the roots,comment on nature of roots of following equations
3x^2-7x+2=0​

Answer 1

----------------------------------------------------------------------
$\bold{answer}$
Here, a=3, b= -7 and c=2

$So, \: Discriminant \: (D) = {b}^{2} - 4c$
$D = ( { - 7)}^{2} - 4(3)(2)$
$= 49 - 24$
$= 25$
----------------------------------------------------------------------

As D>0, the roots of eq. are real and unequal
