Question

the zeroes of the quadratic polynomial x^2-5x+4 are alpha and beta then 1/alpha+1/beta- alpha×bata equals ​

Answer 1

Step-by-step explanation:

let alpha and beta be a and b respectively.

x^2-5x+4

sum of roots= a+b = 5/1

product of roots= ab= 4/1

now, 1/a +1/b -ab

=a+b/ab -ab

=5/4 -4

= -11/4
