Question

if no roots of the quadratic equation x²+px+1=0 is real, then find the value of p

Answer 1

Step-by-step explanation:

I hope you are asking if both roots of eq... is real.

if no roots so d > 0

d = b^2 - 4ac

p^2 - 4 × 1 ×1 > 0

p^2 > 4

p > 2

the value of p should be greater than 2

i.e. 3 , 4 ....infinity

x belongs to ( 2 , infinity )
