计算：(ab-b²)×a-b/ab计算：(ab-b²)×a-b/ab计算：(ab-b²)×a-b/ab(ab-b²)×a-b/ab=a2b-ab2-b2/a=a

ab+a+b+1ab+a+b+1ab+a+b+1ab+a+b+1=a(b+1)+(b+1)=(a+1)(b+1)ab+a+b+1=a(b+1)+b+1=(b+1)(a+1)ab+a+b+1=(ab+a

a+b/2aba+b/2aba+b/2ab因为a＋b≥2√(ab),则：1/(a＋b)≤1/[2√(ab)],所以：2ab/(a＋b)≤2ab/[2√(ab)]=√ab,即：2ab/[a＋b]≤√(a

2AB/A+B2AB/A+B2AB/A+B由(√a+√b)²≥0∴a+b-2√ab≥0∴a+b≥2√ab1/(a+b)≤1/2√ab.∴2ab/a+b≤2ab/2√ab=√ab.所以2ab/

a+b/2aba+b/2aba+b/2ab证明：∵a,b都是正数,且a≠b∴(√a+√b)²≥0∴a+b-2√ab≥0∴a+b≥2√ab1/(a+b)≤1/2√ab.∴2ab/a+b≤2ab

若a>b,ab若a>b,ab若a>b,ab答：a>b,ab0>b|a|-a>b所以：-b>a>-a>baba>ba为正数b为复数|a|则a-a>b;关系-b>a>-a>b

a+ab+b因式分解,a+ab+b因式分解,a+ab+b因式分解,a+ab+b因式分解,无法分解了已经是最简了写错了吧？！a(1+b+b/a),不就完了
