$<marquee behavior=move bgcolor= White > <h1> ☺️☺️HELLO✌️✌️ </h1></marquee>$

Solution:-

Comparing 5x² +17x +6 with ax²+bx+c, we get :--

a= 5, b=17 and c= 6

Therefore,

b²-4ac= (17)²-4×5×6

= 289 -120=169.

169 is a perfect square of 13.

Therefore it's proved.

Thanks!!!

Answer 2

Step-by-step explanation:

a= 5

b=17

c= 6

Hence

........

b²-4ac= (17)²-4×5×6

= 289 -120

=169

= 13^2=13

Hence Proved.....
