If x is real, then the expression (x²+34x-71)/(x²+2x-7)lies b/w 4 and 7lies b/w 5 and 9has no value b/w 4 and 7has no value b/w 5 and 9Plz solve it...

let (x^2 +34x-71)=k(x^2+2x-7),this is a quadratic equation in x which has real roots/values of x if the discriminant, which is a function of 'k' is non-negative, solve this inequality to obtain the answer.
