If `a ,b ,a n dc` are in A.P. and one root of the equation `a x^2+b c+c=0i s2,` the find the other root`dot`

Text Solution

Verified by Experts

From the given infromation,
`4a + 2b + c = 0 and 2b = a + c`
or 5a + 2c = 0
or `(c)/(a) = (-5)/(2)`
Let `alpha` be the other root.
`therefore 2xx alpha = (c)/(a) = - (5)/(2)`
`therefore alpha = -(5)/(40`
