Answer:

The zeroes of the polynomial are 2 and -1/3

Sum of the zeroes = 2 + -1/3

= 2 - 1/3 = 6 - 1/3 = 5/3

i. e., alpha + beta = 5/3

Product of zeroes = 2 × -1/3

= -2/3

i. e., alpha × beta = -2/3

Then the polynomial is of the form,

x² - (alpha + beta) × x + (alpha × beta ) = 0

x² - 5/3 × x + -2/3 = 0

x² - 5x/3 - 2/3 = 0

3x² - 5x - 2/3 = 0

3x² - 5x - 2 = 0

So the polynomial is

3x² - 5x - 2
