Use a recursion tree to give an asymptotically tight solution to the recurrence T (n) = T (\alpha n) + T ( (1 - \alpha)n) + cn T (n) =T (αn)+T ( (1− α)n)+cn, where \alpha α is a constant in the range 0 < \alpha < 1 0 < α <1, and c > 0 c >0 is also a constant. We can assume that 0 < \alpha \le 1 / 2 0

Even if you don't want to draw the Entire recursive Tree, Just visualize it as the Root Node is Working on O (n2) complexity where as the child will work on 9/16*n2 Complexity that will be decreasing until you reach the farthest child or we can say the Leaf. And that certainly will be less than O (n2) and we can neglect it.
