$N = \frac{t^{2} - t}{2}$

Step 1

Factor $t$ out of $t^{2}$ .

$N = \frac{t \cdot t - t}{2}$

Step 2

Factor $t$ out of $- t$ .

$N = \frac{t \cdot t + t \cdot - 1}{2}$

Step 3

Factor $t$ out of $t \cdot t + t \cdot - 1$ .

$N = \frac{t (t - 1)}{2}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
