Question

if √p + √q - √r =0 then find the value of( p + Q - r)

Answer 1

Hello Dear !
_________________________________________________________
√p + √q - √r - 0 _____(1) 
√p + √q = √r     _____(2)
squaring both sides 
p + q + 2√p√q = r 

p + q - r = -2√p√q 
_________________________________________________________

Answer 2

√p+√q-√r =0

√p+√q = √r

Squaring on both sides,

(√p+√q)² = √r²

√p²+√q²+2(√p)(√q) = r

p+q+2√pq = r

p+q-r = -2√pq

Hope it helps
