Algebra Examples

$x (y - 1) + y (y - 1)$

Step 1

Factor $y - 1$ out of $x (y - 1)$ .

$(y - 1) x + y (y - 1)$

Step 2

Factor $y - 1$ out of $y (y - 1)$ .

$(y - 1) x + (y - 1) y$

Step 3

Factor $y - 1$ out of $(y - 1) x + (y - 1) y$ .

$(y - 1) (x + y)$

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