Hi there !!
Zeroes = 1/2+2√3 and 1/2-2√3
Sum of zeroes = 1/2+2√3 + 1/2-2√3
= 1/2 + 1/2
= 1
Product of zeroes = [1/2+2√3] x [1/2-2√3]
= [ 1/2 ] ² - [ 2√3 ]²
= 1/4 - 12
= 1/4 - 12 x 4/4
= 1/4 - 48 / 4
= -47 /4
Quadratic polynomial:-
x² - [ sum of zeroes ]x + [ product of zeroes ]
=x² - x + -47/4
Zeroes = 1/2+2√3 and 1/2-2√3
Sum of zeroes = 1/2+2√3 + 1/2-2√3
= 1/2 + 1/2
= 1
Product of zeroes = [1/2+2√3] x [1/2-2√3]
= [ 1/2 ] ² - [ 2√3 ]²
= 1/4 - 12
= 1/4 - 12 x 4/4
= 1/4 - 48 / 4
= -47 /4
