ith mulher and came​

Answer 1

Note:

Let a and b be the roots of the given quadratic polynomial.

Given:

(1) a+b=0

(2) ab= -1

To Find:

Quadratic polynomial=?

Formula:

x²-(a+b)x+ab=0

Solution:

As per the formula,

The required quadratic polynomial:

x²-x-1=0

Answer 2

Answer:

let a , b the root of quadratic polynomial ,where

a+b = 0

ab = -1

from of quadratic polynomial

$x ^{2} + (a + b) x - ab \\ x ^{2} - 1 = 0 \: be \: the \: form \: of \: quadratic \: polynomial$
