Découvrir 101 Imagen Formule Coefficient Binomiaux Fr Thptnganamst Binomial expansion is one special area in algebra.here i have explained the basic concepts and discussed a set of questions.please continue to watch part 2 o. The binomial theorem tells us how to expand expressions of the form (a b)ⁿ, for example, (x y)⁷. the larger the power is, the harder it is to expand expressions like this directly. but with the binomial theorem, the process is relatively fast! created by sal khan. Now on to the binomial. we will use the simple binomial a b, but it could be any binomial. let us start with an exponent of 0 and build upwards. exponent of 0. when an exponent is 0, we get 1: (a b) 0 = 1. exponent of 1. when the exponent is 1, we get the original value, unchanged: (a b) 1 = a b. exponent of 2. Our pattern here is 0, 4, 4, 0. once again, we can see this as a block of 4. dividing the exponent by 4 and having a remainder of 1 or 0 means the tens digit will be 0. dividing the exponent by 4 and having a remainder of 2 or 3 means the tens digit will be 4. 1993 divided by 4 yields a remainder of 1.

Example 25.2.2. determine: the 4 th term in the binomial expansion of (p 3q)5. the 8 th term in the binomial expansion of (x3y − 2x2)10. the 12 th term in the binomial expansion of ( − 5a b7 − b)15. solution. we have a = p and b = 3q, and n = 5 and k = 4. The binomial coefficients are the integers calculated using the formula: (n k) = n! k!(n − k)!. the binomial theorem provides a method for expanding binomials raised to powers without directly multiplying each factor: (x y)n = n ∑ k = 0(n k)xn − kyk. use pascal’s triangle to quickly determine the binomial coefficients.
