Question

Is there any real value of p for eqn x2 +2x+ (p2-1)=0

Answer 1

Answer:

yes as i think it is possible

Step-by-step explanation:

compromising the question  x2 +2x+ (p2-1)=0 to ax^2+bx+c

then we obtain that

a=1                                            ...........(1)

b=2                                           ............(2)

c=p2-1                                       .............(3)

for real value

D<0

by the quadratic formula

D= b^2-4(a)(c)

substituting the value of (1)(2)&(3)

D= (2)^2-4(1)(p2-1 )

where  D<0

so

4-4(p2-1)<0

4-4p2+4<0

8-4p2<0

4p2<8

p2<8/2

p2<4

p<root under 4/2

p<2

and as i think it can be possible if u satisfied pls mark it brainly

hope it helps to u
