*"Sheraz’s Identity: Powerful New Algebra Formula by Muhammad Sheraz for Fast Cube Expansion"*
*📢✨ Discover Sheraz’s Identity No.1 – A Powerful New Math Shortcut by Muhammad Sheraz (Pakistan)* *🧮 Formula Name:* *Sheraz’s Identity No.1* *📘 The Formula:* *(a + b)³ + (a - b)³ = 2a³ + 6ab²* *💡 Description:* Sheraz’s Identity is a time-saving algebraic shortcut discovered by *Muhammad Sheraz* from *Pakistan* 🇵🇰. This identity simplifies cube expressions quickly and efficiently—especially useful in competitive exams and mental math. --- *📚 Proof of Sheraz’s Identity:* Start by expanding both cube terms: - (a + b)³ = a³ + 3a²b + 3ab² + b³ - (a - b)³ = a³ - 3a²b + 3ab² - b³ Now, add both expansions: *(a + b)³ + (a - b)³ = a³ + a³ + 3ab² + 3ab² = 2a³ + 6ab²* ✔ *Hence Proved:* *(a + b)³ + (a - b)³ = 2a³ + 6ab²* *🎯 Applications:* - Algebraic shortcuts - Competitive exams (FPSC, NTS, CSS, etc.) - Mental math techniques - Quick simplification in expressions --- *🔬 Introduced by:*...
