Answer 2

Answer:

$Roots \: of \: given \\Qudartic \: equation\: are\\Real \: and \: distinct$

Step-by-step explanation:

$Compare \: given \: \\Quadratic \: equation \: 4x^{2}-12x-9 =0\:with\\ \:ax^{2}+bx+c=0,we \: get$

$a=4,\:b=-12,\:c=-9$

$Discreminant (D)=b^{2}-4ac\\=(-12)^{2}-4\times 4\times (-9)\\=144+144\\=288$

$D>0$

Therefore,

$Roots \: of \: given \\Qudartic \: equation\: are\\Real \: and \: distinct$
