The binomial theorem states a formula for expressing the powers of sums. The most succinct version of this formula is shown immediately below. Isaac Newton wrote a generalized form of the Binomial Theorem.
A binomial is an algebraic expression containing 2 terms. Clearly, doing this by direct multiplication gets quite tedious and can be rather difficult for larger powers or more complicated expressions. We note that the coefficients the numbers in front of each term follow a pattern. You can use this pattern to form the coefficients, rather than multiply everything out as we did above.
The calculations get longer and longer as we go, but there is some kind of pattern developing. The Binomial Theorem. An exponent of 2 means to multiply by itself see how to multiply polynomials :. Now, notice the exponents of a. They start at 3 and go down: 3, 2, 1,

4. The Binomial Theorem
Note: Binomial Theorem is different than binomial distribution. Binomial Theorem is a quick way of expanding a binomial expression with that are raised to large powers. This theorem is a really important topic section in algebra and has application in Permutations and Combinations, Probability, Matrices, and Mathematical Induction.

Assume that you guess on each question of a multiple choice test. There are 12 questions and each question has 4 possible answers. What is the probability of getting exactly 8 answers correct? Thus, if we want to find the coefficient of ,. This question requires the application of the binomial theorem for probability. In order to determine the probability of getting exactly 6 questions right, we must remember the formula for this theorem:. Where is the number of trials total questions , is the number of successes correct answers , is the probability of success in one trial chance of answering a question correctly , is the probability of failure in one trial chance of answering a question incorrectly , and is the probability of getting questions correct out of total questions.
