 If `m_1`
and `m_2`
are the roots of the equation `x^2-a x-a-1=0`
, then the area of the triangle formed by the three straight lines `y=m_1x ,y=m_2x ,`
and `y=a(a!=-1)`
is
 `(a^2(a+2))/(2(a+1))ifa >-1`

 `(-a^2(a+2))/(2(a+1))ifa >-1`

 `(-a^2(a+2))/(2(a+1))if-2 lt a lt -1` `(a^2(a+2))="" (2(a+1))ifa lt -2` lt ="" b="" gt
