ÖRNEKLER: ÖZDEŞLİK ÖRNEKLERİ

Aşağıdaki eşitlikler, özdeşliktir.

• x + 2 = 2 + x
• xy(y – 1) = x(y² – y)
• x⁴ – 1 = (x² – 1)(x² + 1)
• a(b² – b) = b(ab – a)
• x⁶ – 4x³ + 4 = (2 – x³)²

• (3x – 1)² = (1 – 3x)²
• 7(a² – a) = a(7a – 7)
• 2x⁴ – x³ + 1 = 2(–x)⁴ + (–x)³ + 1
• z³t + z²t² + zt³ = zt(z² + zt + t²)
• 100 – b⁴ = (10 – b²)(b² + 10)

• (a – b²)² = a² – 2ab² + b⁴
• (x + 1)(x + 2) = (–x – 1)(–x – 2)
• 30z² – zt² = (30z – t²)z
• mn² – m³ = m(n – m)(n + m)
• x²t – 1 = –1 + tx²
• t² – t⁰ = (t¹ + t⁰)(t¹ – t⁰)
• 2⁴ – t⁴ = (4¹ – t²)(2² + t²)
