**Solution:**

**The following solution is the same just replace alpha by p and beeta by q !!**

**Given that:**

*p* and *q* are the zeros of polynomial *f* (*x*) = 4*x* ^{2} – 5*x* – 1,

To find: *p* ^{2} *q* + *pq* ^{2} = *pq* (*p* + *q*)

Since, *p* and *q* are the zeros of polynomial *f* (*x*) = 4*x* ^{2} – 5*x* – 1
