Question

If p and q are the zeroes of the quadratic polynomial f(x) = x^2 + x - 2, then find a polynomial whose zeroes are 2p + 1 and 2q + 1​

Answer 1

Step-by-step explanation:

zeroes of second polynomial => (2p+1)(2q+1)

=>1+2(p+q)+4pq -----(1)

now if you see the first,

f(x) = x²+x-2

here ...

p+q = -1

PQ = -2

substitute these values,

= 1-2-8

= 1-10

= -9..
