Question

if the roots of equation x²-5x+16=0 are a,b and roots of equation x²+px+q=0 are a²+b², ab/2 then
(a)p=1,q=-56
(b)p=-1,q=-56
(c)p=1,q=56
(d)p=-1,q=56​

Answer 1

Answer:

if the roots of equation x²-5x+16=0 are a,b and roots of equation x²+px+q=0 are a²+b², ab/2 then

(a)p=1,q=-56

(b)p=-1,q=-56

(c)p=1,q=56

(d)p=-1,q=56

Step-by-step explanation:

if the roots of equation x²-5x+16=0 are a,b and roots of equation x²+px+q=0 are a²+b², ab/2 then

(a)p=1,q=-56

(b)p=-1,q=-56

(c)p=1,q=56

(d)p=-1,q=56
