A General Note: The (r+1)th Term of a Binomial Expansion The(r+1)th(r+1)thterm of the binomial expansion of(x+y)n(x+y)nis: (nr)xn−ryr(nr)xn−ryr How To: Given a binomial, write a specific term without fully expanding. ...
a) Find the coefficient of x7in the binomial expansions of (3-x)10. b) Find, in simplified form, the fourth term in the binomial expansion of (4-x)−1/2. For what values of x is this expansion valid? Binomial Theorem A polynomial that has exactly two terms is called ...
Using the Binomial Theorem, the expansion of (1−x)n is given by:(1−x)n=n∑k=0(nk)(−x)k=n∑k=0(nk)(−1)kxkThis means that the coefficient of xk in (1−x)n is (nk)(−1)k. Step 2: Multiply by (1+x)Now, we need to multiply (1+x) with the expansion ...
This problem involves the application of binomial theorem to find the coefficient of a term. The binomial theorem simply helps us to find the required coefficient easily using combinatorics. Note the formula of the binomial theorem is, {eq}\displaystyle (a+b)^n = \sum_{i=0}^...

common factors and prime factors in maths. factors in algebra like natural numbers, factors are also defined for algebraic expressions. for example, the factors of 8x are 1, 2, 4, 8, x and 8x. here, 8x is an algebraic expression, where 8 is the coefficient of variable x. 8x = 8 ...
The rational zero theorem is a very useful theorem for finding rational roots. It states that if any rational root of a polynomial is expressed as a fraction pq in the lowest terms, then p will be a factor of the constant term and q will be a factor of the leading coefficient. ...
