Question

If a and b are the zeroes of polynomial P(x) =2x^2-5x+k such that ab=1. find the value of k.

Answer 1

Heya !!!



P(X) = 2X² - 5X + K



Here,



A = 2 , B = -5 and C = K



Alpha × Beta = C/A




1 = K /2



K = 2.





HOPE IT WILL HELP YOU..... :-)

Answer 2

Hey !!!

i am considering alpha as ' a '
and bita as ' b '

Given , ab = 1

•°• we know that

product of zeroes=constant term/cofficient of x²

that means ,

=> k/2 = 1

=> k = 2
