Answer 1

Step-by-step explanation:

Rationalise x by:

$\sqrt{p + 2q} + \sqrt{p - 2q}$

u I'll get

$x = \frac{2p -2 \sqrt{ {p}^{2} - 4 {q}^{2} } }{2p + 4q} \\ x = \frac{p - \sqrt{ {p}^{2} - 4 {q}^{2} } }{p + q}$

This looks the same as: the quadratic equation formula... I

i.e

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a}$

Same down their

Answer 2

Answer:

Hello mate ✌️

Step-by-step explanation:

Given,

x=√7/5 and 5/x = p √7

since

5/x= p√7

5/√7/5 =p √7

p √7 = 25/√7

p = 25/√7×√7

p = 25/ (√7)²

p = 25/7

hope it will be helpful to you ✌️
