Q.
Statement-1: Number of integral values of $m$ for which exactly one root of the equation $x^2-2 m x+m^2-1=0$ lies in the interval $(-2,4)$ equals 2 .
Statement-2: Let $f(x)=a x^2+b x+c$ where $a, b, c \in R$ and $a \neq 0$. If $f(d) f(e)<0$ then the equation $f(x)=0$ has exactly one root in $(d, e)$.
