Question

The quadratic equation 2x2 + px + 3 = 0 has two equal roots. Find the value of p.​

Answer 1

Answer:

As the equation has equal roots

Answer 2

Answer:

{p = ±2√6 }

Step-by-step explanation:

2x² +px +3=0

∝+β=-p/2

since ∝=β

2β =-p/2

β=-p/4

∝β =c/a=3/2

β² =3/2

(-p/4)²= 3/2

p²/16 =3/2

p² =24

p =±√24

{ p= ± 2√6 }
