Exploring the Binomial Theorem

What is the binomial theorem?

• The binomial theorem states that (a + b)^n = Σ (n choose k) * a^(n-k) * b^k.

• The binomial theorem states that (a - b)^n = Σ (n choose k) * a^(n+k) * b^k.

• The binomial theorem is used to calculate the area of a circle.

• The binomial theorem is a method for solving quadratic equations.

State the general form of the binomial expansion.

• (a + b)^n = Σ (C(n, k) * a^(n+k) * b^k) for k = 0 to n

• (a + b)^n = (a^n + b^n) for n > 0

• (a + b)^n = Σ (C(n, k) * a^(n-k) * b^k) for k = 0 to n

• (a + b)^n = C(n, k) * a^k * b^(n-k) for k = 1 to n
