Question

the roots alpha and beta of the quadratic equations x²-5 X+ 3(k- 1)= 0 are such that alpha beta = 1 .find the value of k ​

Answer 1

Answer:

generally alpha *beta =c/a

given equation is x²-5x+3(k-1)=0

alpha *beta =3(k-1)/1

given that alpha *beta=1

there fore 3(k-1)=1

k-1=1/3

k=1+1/3

k=4/3
