The roots α and β of the quadratic equation x2 -5x+3(k-1)=0 are such that αβ=1. Find the value k.
​

Answer 1

Answer:

Step-by-step explanation:

so we know , alpha * beta= c/a

where ax^2+bx+c =0 is a quadratic expression

now alpha * beta = 1

so in your question,

c=3k-3

a=1

so

1=3k-3

k=4/3
