Detailed Example
Mathematical expansion of polynomial powers.
Problem: Expand (1x + 2y)² using the Binomial Expansion Calculator.
Solution: The calculator identifies nCr coefficients and applies the algebraic power rule to each term in the series.
Step 1: 2C0 * (1x)² * (2y)⁰ = 1 * 1x² * 1 = 1x².
Step 2: 2C1 * (1x)¹ * (2y)¹ = 2 * 1x * 2y = 4xy.
Step 3: 2C2 * (1x)⁰ * (2y)² = 1 * 1 * 4y² = 4y².
Step 2: 2C1 * (1x)¹ * (2y)¹ = 2 * 1x * 2y = 4xy.
Step 3: 2C2 * (1x)⁰ * (2y)² = 1 * 1 * 4y² = 4y².
Final Result: 1x² + 4xy + 4y². This represents the full algebraic series expansion for your provided expression across the numeric plane.
