Question

find the values of p for which equation 2x^2 + px +3 = 0 have equal roots​

Answer 1

Answer:

p= 2√6 or 4.9

Explanation:

We are provided with the equation 2x^2+px+3=0

On comparing it with ax^2+bx+c=0 ,we get;

a=2, b=p, c=3

Since,the equation has equal roots, then

D = b^2 - 4ac = 0

=> (p)^2 - 4(2)(3) = 0

=> p^2 = 24

=> p = √24 = 2√6

or p = 4.9
