Question

if alpha and beta aree the two zeroes of the polynomial 2x^2+3x +5 then the value of 2/alpha and 1/beta, without actually finding the zeroes of tue polynomial ​

Answer 1

Given that

p(X) = 2x^2+3x+5

To find the Beta with out finding zeroes

The coefficients of p(X) = 2x^2+3x+5

= a = 2 ; b= 3 ; c = 5

if alpha 2/alpha = 2/ 2 ( since p(X) = Coefficient of X / coefficient of x^2
