Answer 1

Answer:

Step-by-step explanation:

First quadratic equation is x2-x+p=0,a and b are the roots of this eqn,so a+b=1,a*b=p,b=1-a

Again for second quadratic x2-4x+q,C and d are the roots of the equation,so c+d=5 c*d=q,d=4-c.

So if we will look at the equation

b=1-a,d=4-c we can put some values which should be GP,so start from 1,if we will put 1 then b=0,so you can't put 1

Then try -1 we will b=2,

From geometric progression we can say that it's r(common ratio)is -2 and by that if we will find C &d we will get -4&8.

If we will put c&d value in the above equation of c&d then it is satisfied thus whatever we have assumed is right ,so a=-1,b=2,C=-4,d=8

From quadratic we know that p=a*b,p=-2

q=c*d,q=-32
