If one zero of the polynomial 5z2+13z-p is the of resipocal the other, then find p
Asked by gauravmaurya45.tl | 02 May, 2020, 07:38: PM
Expert Answer
Given polynomial is P(x) = 5z2 + 13z - p
Let one of the zeroes be 'a'
The other zero must be 1/a
Using the relationship between the roots and coefficients of polynomial we have
a × 1/a = -p/5
→-p/5 = 1
→ p = -5
