A body is projected vertically upwards. If $ t_1$ and $t_2$ be the times at which it is at height h above the point of projection while ascending and descending respectively. then h is,

If the roots of this equation are $t_1$ and $t_2$ then using the fact that the product of roots is equal to c/a for the equation $ax^2 +bx+c=0$ , we get
