If α, β are the zeros of a polynomial such that α + β = −6 and αβ = −4, then write the polynomial.

योग

उत्तर

Let S and P denotes respectively the sum and product of the zeros of a polynomial

We are given S = -6 and P = - 4. Then

The required polynomial  g(x) is given by

`g (x) = x^2  -Sx + p`

`g (x) = x^2 - (-6)x + ( - 4)`

`= x^2 + 6x - 4`

Hence, the polynomial is  `x^2 + 6x - 4`
