Question

QIS Obtain all veroes of the polynomial( 2-4-*'+2), if two of its zeroes are V2 and -v2​

Answer 1

Step-by-step explanation:

a quadratic equation, ax

2

+bx+c=0,

The sum of the roots=

a

−b

and product of the roots is

a

c

Here sum of roots= α+β=

2

−5

Product of roots=αβ=

2

1

Therefore,α+β+αβ=

2

−5

+

2

1

⇒ α+β+αβ=−2
