1. Binomische Formel: & ${\left(a + b \right)}^{2} = {a}^{2} + 2ab + {b}^{2}$ \\
2. Binomische Formel: & ${\left(a - b \right)}^{2} = {a}^{2} - 2ab + {b}^{2}$ \\
3. Binomische Formel: & $\left(a + b \right) \left(a - b \right) = {a}^{2} - {b}^{2}$ \\
Bnomischer Lehrsatz: & ${\left( a + b \right)}^{n} = \sum _{ k = 0 }^{ n }{ { a }^{ n-k }{ b }^{ k } } $ \\
\end{tablebox}
Den Binomischen Lehrsatz kannst du auch aus dem pascalschen Dreieck entnehmen.
