Factorization (X-Y) ^ 2-4 (X-Y) - A ^ 2 + 4

Factorization (X-Y) ^ 2-4 (X-Y) - A ^ 2 + 4


(X-Y) ^ 2-4 (X-Y) - A ^ 2 + 4 transfer
=(X-Y) ^ 2-4 (X-Y) + 4-A ^ 2 complete square
=[(x-y)-2]²-a²
=(x-y-2) &# 178; - A & # 178; square difference
=(x-y-2+a)(x-y-2-a)



（a-b）（x-y）-（b-a）（x+y）


（a-b）（x-y）-（b-a）（x+y），=（a-b）（x-y）+（a-b）（x+y），=（a-b）（x-y+x+y），=2x（a-b）．



Factorization of A3 (X-Y) - 3a2b (Y-X) into______ ．


A3 (X-Y) - 3a2b (Y-X) = A3 (X-Y) + 3a2b (X-Y) = A2 (X-Y) (a-3b)



Factorization: 9-A & sup2; + 4ab-4b & sup2;
