Question

If px^2-2√5px+15=0 has two equal roots then find the value of p.

Answer 1

Answer:

Step-by-step explanation:

px²-2√5px+15=0

Equation has equal roots

So discriminant=0

Discriminant=b²-4ac

(-2√5p)² - 4×p×15=0

20p²- 60p=0

20p(p-3)=0

Equate with 0

20p=0

p=0

Not possible

p-3=0

p=3
