Question

Find the value of k for which the sum of the zeroes of quadratic polynomial kx^2-3x+5 is 1

Answer 1

HEY FRIEND

HERE IS YOUR ANSWER

kx²-3x+5

a=k, b= -3 and c=5

SUM OF ZEROES =1

WE KNOW THAT :

SUM OF ZEROES = -b/a

1= -(-3)/k

1=3/k

k=3

HOPE THIS HELPS YOU

Answer 2

Hey!

_____________________________________________________________________________________________

kx² - 3x + 5 = 1

ax + bx + c = 0

a = k

b = -3

c = 5

[ Sum of zero = 1 ]

•Sum of zero :-

=> α + β = -b ÷ a

=> 1 = -(-3) ÷ k

=> 1 = 3 ÷ K

=> K = 3
