Answer 2

$hey \: dear \: here \: is \: your \: answer$

⭐⭐<==================>⭐⭐


The given quadratic equation is
px²-2√5px+15

comparing the given quadratic equation with
ax²+bx+c=0, we have
a=p
b=-2√5
c=15

Now discriminant (D)=b²-4ac
=(-2√5p)²-4(p)(15) =20p²-60p
we know that when roots are equal then discriminant is zero.
•°• D=0
=>20p²-60p=0
=>20p(p-3)=0
=>p-3=0
=>P=3 answer.
