Answer:

The sum if the zeroes (α+β) =  \dfrac{-1}{2}

Product of the zeroes (αβ) =  \dfrac{1}{3}

so,

The quadratic equation

= k [x² - (α+β)x + αβ] {where k is constant}

= k [x² - (  \dfrac{-1}{2} x) +  \dfrac{1}{3} ]

= k [ x² +  \dfrac{1}{2} x +  \dfrac{1}{3} ]

Lcm of 2 and 3 is 6

= k [ x² +  \dfrac{3x  + 2}{6}  ]

=  \dfrac{1}{6} [x² + 3x + 2 ]

so , the polynomial is x² + 3x + 2

Answer:

hey mate here is your answer.

Step-by-step explanation:

The two zeroes are given -1/2 and 1/3

first,we find their sum = -1/2+1/3

= -1/6

second, we find their product = -1/2×1/3

= -1/6

Now, we using quadratic polynomial

=k( x²-(a+b)x+ab)

here, a+b is sum of zeroes or roots.

and ab is product of zeroes or roots.

So,on putting values

= k (x²-(-1/6)x+(-1/6))

= k(x² +1/6x-1/6)

here ,k=6

so,equation is 6x²+x-1

hope it helps you.

plz mark it as brainliest.
