1. The quadratic polynomial whose sum of zeroes is 3 and product of zeroes is -2 is:
(a) x2 + 3x - 2
(b) x2 - 2x + 3
(C) x2 - 3x + 2
(d) x2-3x - 2​

Answer 1

Answer:

(c)

Step-by-step explanation:

Correct option isC=x2−3x+2

Let α and β are the roots of given Quadratic polynomial.

Given:

α+β=3,αβ=2

Quadratic polynomial:

x2−(α+β)x+(αβ)

∴ Polynomial is x2−3x+2

Option C is correct.
