Question

if p+1/p=3 then psquare+1/psquare​

Answer 1

Step-by-step explanation:

p+1/p=3

psquare+1 =3p

psquare-3p+1=0

psquare-3p+(3/2) square-(3/2)square+1=o

(p-3/2)square=(3/2)square -1

(p-3/2)square= 9/4-1

((p-3/2)square)^1/2=√5/2

p-3/2=√5/2

p=√5/2+3/2

psquare+1/psquare

(√5/2+3/2)^2 +1/(√5+3/2)^2

= (14+6√5)/4+1/(14+6√5)/4

=(14+6√5)/4+4/(14+6√5)

=16+(14+6√5)square

=16+196+180+168√5

=392+168√5

=767.65
