Question

If 2 and -1/2 as the sum and product of its zeros respectively then the quadratic polynomial f(x) is:

Answer 1

it is given that 2 and -1/2 as the sum and product of its zeros respectively.

So the sum of zeros  = $\alpha$ + $\beta$ = 2 and ,

The product of zeros = $\alpha$$\beta$ = -1/2

Then the quadratic equation is ,

$x^{2}$ - (  $\alpha$ + $\beta$ )x + ( $\alpha \beta$ )

$x^{2}$ - ( 2 )x + ( -1/2 )

$x^{2}$ - 2x - 1/2

hence the the quadratic polynomial f(x) =  $x^{2}$ - 2x - 1/2
