Question

If the equation 5x2-px+1=0 has equal roots then value of p

Answer 1

Step-by-step explanation:

given quadratic equation

5x²-px+1=0

compare with ax²+bx+c=0

then we get a=5 b=-p and c=1

condition for having equal roots

b²-4ac=0

(-p)²-4(5)(1)=0

p²-20=0

p²=20

p=root20

p=root4*5

p=2root5

hope this helps you...
