Question

the sum of the roots x2-mx+n=0 is k times their difference
​

Answer 1

Step-by-step explanation:

Given equation

$x {}^{2} - mx + n = 0$

Here a = 1, b = – m and c = n

Roots of the equation are :

x = – b / a and x = c / a

x = – (– m) / 1 and x = n / 1

x = m and x = n

According to question

m + n = k ( m – n)

=> k = (m + n) / (m – n)
