It opens downwards so it looks like this “n”. That is because a in the formula is a negative number in this situation
(5,12,13) is a right triangle and can be constructed.
All the others do not satisfy the triangle inequality, i.e. the sum of two short sides must exceed the long side in order for the triangle to be constructed.
Examples:
2+11<15, so no
3+7<11, so no
4+8<15, so no
but 5+12>13 so yes, it can be constructed.
A graphing calculator is a great help for problems of this nature.
x ∈ {-5.63, -0.55, 2.59}
