ROOTS LIE IN AN INTERVAL
Here basically we will discuss different necessary and sufficient conditions we should impose on a quadratic equation ax2 + bx + c = 0 such that roots of the given equation lies in a
Illustrations on Roots in an Interval
Illustration -: For the quadratic equation x2 – (m – 3)x + m = 0, find the value of m for which
(i) one root is smaller than 2 and the other is greater than 2
(ii) both roots are grater than 2
(iii) both roots lie in (1, 2)
(iv) exactly one root lie in (1, 2)
