Method of Solution:


Equation : x²+4√3x+3

For the Zeroes of Polynomial f(x)= (x²+4√3x+3)

Zeroes of Polynomial = -b/a -(Coefficient of x)/Coefficient of x²


Sum of Zeroes of Polynomial = -4/√2 ÷1 => -4/√2

Sum of Zeroes = -4/√2

Product of Zeroes of Polynomial = C/a =(Constant term)/Coefficient of x²

[ Product of Zeroes = 3/1 => 1 ]

Therefore, We have obtained (a+ß ) = 4/√2

(aß) = 3


According to the Question Statement!

Statement: find the value of alpha + beta - alpha beta

Substitute the obtained value,

alpha + beta - alpha beta

(4/√2) - (1)

=>
 \frac{4}{ \sqrt{2} }  - 1 \\  \\  \frac{4 -  \sqrt{2} }{ \sqrt{2} }

poongodi6: where do we get sum of coffiecient 4√2
poongodi6: in the question sum of poly = -b÷a which is -4√3÷1
