Question

Q1) solve from identies and answer should be
$+ 2 \sqrt{35}$
​

Answer 1

Answer:

Step-by-step explanation:

(p+1/p)^2=144

p^2+1/p^2=144-2 =142

(p-1/p)^2= p^2+1/p^2-2

=142-2

=140 so

(p-1/p)=root(140)

= root(4*35)

=2root35

Answer 2

$p + \frac{1}{p} = 12$

$by \: \: \: ( {a}^{2} - {b}^{2} ) = (a + b)(a - b)$

$so$

$p - \frac{1}{p} = 2 + \sqrt{35}$
