Factor (x-y)^2-3(x-y)

${(x - y)}^{2} - 3 (x - y)$

Step 1

Factor $x - y$ out of ${(x - y)}^{2}$ .

$(x - y) (x - y) - 3 (x - y)$

Step 2

Factor $x - y$ out of $- 3 (x - y)$ .

$(x - y) (x - y) + (x - y) \cdot - 3$

Step 3

Factor $x - y$ out of $(x - y) (x - y) + (x - y) \cdot - 3$ .

$(x - y) (x - y - 3)$
