Question

if p,q r the roots od quadratic equation x^2+2bx+c=0 and k log (square root of y-p +square root of y-q)=log 2+log(y+square root y^2 +2by+c) where k=

Answer 1

Answer:

p+q=−2b;pq=c

2log(

y−p

+

y−q

)

=log(2y−p−q+2

(y−p)(y−q)

)

=log2(y+b+

y

2

+2by+c

)

=log2+log(y+b+

y

2

+2by+c

)

Answer 2

wher k=2. May it help u.thank u
