How to calculate X & # 178; ≤ 9


-3《x



Find (a + b) &# 178; (M + n) &# 178; - 2 (A & # 178; - B & # 178;) (M & # 178; - N & # 178;) + (a-b) &# 178; (m-n) &# 178;


The original formula = [(a + b) (M + n)], # 178; - 2 [(a + b) (M + n)] × [(a-b) (m-n)] + [(a-b) (m-n)], # 178;
=[(a＋b)(m＋n)－(a－b)(m－n)]²
=[(am＋an＋bm＋bn)－(am－an－bm＋bn)]²
=[2an＋2bm]²
=4(an＋bm)²
