Question

If p/q=(2/3)³÷(2/3)⁰, find the value of (p/q)²...
plz answer me guys fast.....​

Answer 1

ANSWER

Given that

p(x)=ax

3

+bx

2

+cx+d .........(1) where a



=0 is a cubic polynomial

And p,q,r are the zeroes of the polynomial p(x)

We all know that

p+q+r=

a

−b

= Sum of the roots

pq+qr+rp=

a

c

= Product of roots taken two at a time

pqr=

a

−d

= product of roots

In the Question

p

1

+

q

1

+

r

1

=

pqr

pq+qr+rp

=

a

−d

a

c

=

d

−c
